Texas Cichlid – Herichthys cyanoguttatus

Among New World cichlids, the Texas Cichlid Herichthys cyanoguttatus stands out as a powerful, intelligent and remarkably beautiful species. Its metallic spots, expressive behaviour and strong territorial instincts make it a favourite for advanced aquarists who appreciate character as much as colour. In this article we will explore how to keep this fish successfully, how to design a suitable aquarium and which equipment and accessories, available at MB Store, will help you create stable and attractive conditions for this fascinating species.

Origin, appearance and natural behaviour of the Texas Cichlid

The Texas Cichlid is the only naturally occurring cichlid native to the United States, found mainly in the lower Rio Grande drainage in Texas and northern Mexico. It inhabits slow to moderately flowing rivers, backwaters and oxbow lakes with sandy or muddy bottoms, submerged roots and patches of aquatic vegetation. Water conditions in these habitats vary with the seasons, and the species is adapted to a wide range of parameters, a trait that translates into high aquarium hardiness.

Adult Texas Cichlids are robust, oval-shaped fish with a powerful head and a slightly arched back. Their base colour is usually pearly grey to greenish, decorated with numerous iridescent turquoise or blue spots that gave rise to the scientific name cyanoguttatus, meaning blue-spotted. Mature males often develop a pronounced nuchal hump and slightly elongated fins, while females tend to be more compact and rounded. In good conditions, colours intensify significantly, and black markings along the flanks become more distinct, especially during courtship and spawning.

Behaviourally, this species is highly territorial and intelligent. It learns to recognise its keeper, often coming to the front glass during feeding time and reacting clearly to movements outside the tank. At the same time, it can be aggressive towards conspecifics and other fish, particularly in smaller aquariums. Hierarchies are firmly established, and weaker individuals may be bullied if there is insufficient space or hiding spots. Observing the interactions, body language and colour changes of Texas Cichlids can be deeply rewarding, but it also demands responsible tank planning.

Tank size, layout and substrate for Herichthys cyanoguttatus

Because of their size and temperament, Texas Cichlids should never be kept in small aquariums. A single adult requires at least 200 litres, while a compatible pair or community with other robust cichlids will thrive more comfortably in aquariums from 300 to 450 litres and up. The larger the volume, the easier it is to stabilise water parameters, distribute territories and reduce aggression. MB Store offers a wide selection of sturdy glass aquariums in these volume ranges, suitable both for standalone setups and integrated furniture solutions for living rooms or dedicated fish rooms.

The layout should take into account the natural behaviour of digging and territorial defence. A sandy or fine gravel substrate allows the fish to excavate pits during courtship and spawning, an activity that plays an important role in their behavioural repertoire. Avoid sharp or very coarse substrates that can damage the mouth or gill covers while digging. It is also wise to secure decorations firmly, as a determined Texas Cichlid is capable of moving surprisingly large stones and uprooting plants while reshaping its territory.

Hardscape is essential. Large rocks, inert driftwood and robust ceramic caves help to structure the aquarium and break the direct line of sight between territories. This reduces constant visual contact and lowers stress among tank mates. Piles of rock can be arranged to create tunnels and sheltered areas where subdominant fish can withdraw when harassed. At MB Store you will find a broad range of decorative stones, roots and artificial caves that are safe for aquarium use and do not alter water chemistry in an undesirable way.

Live plants in a Texas Cichlid aquarium are possible, but they require careful selection. Many delicate species will be shredded, eaten or uprooted. Opt instead for hardy, tough-leaved plants such as Anubias, Java fern or certain species of Vallisneria. These can be attached to wood and rocks rather than planted directly in the substrate, which helps protect them from digging. Even then, you should be prepared for some rearranging by the fish, especially during breeding periods when territorial instincts peak. Artificial plants can also be used to add visual interest while avoiding damage to live specimens.

Water parameters, filtration and maintenance

Texas Cichlids are adaptable but show their best colours and health in stable, clean water. They prefer slightly alkaline conditions with a pH between 7.0 and 8.0 and medium to moderately hard water. Temperature should generally be kept between 23 and 28 degrees Celsius. Maintaining stable temperature is easier with a reliable heater and a precise thermometer, both of which are available in various wattages and designs at MB Store, allowing you to match the equipment accurately to your tank size and room conditions.

Because these fish are large, active feeders and enthusiastic diggers, they produce a significant bioload. This makes strong and efficient filtration absolutely essential. A spacious internal filter may be adequate for smaller setups, but for larger tanks, external canister filters are strongly recommended. They provide larger volumes of biological media, better mechanical filtration and more flexible placement of inlets and outlets. At MB Store you can choose from a range of filters and filter media suitable for heavily stocked cichlid aquariums, including high surface area ceramic rings and sponges that support beneficial bacterial colonies.

Aim for a filter that can turn over the full volume of the tank at least four to six times per hour. Strong water movement not only helps keep detritus suspended so it can be removed by the filter, but also ensures adequate oxygenation. However, it is preferable to disperse the outflow to avoid a single, excessively strong current that might constantly stress the fish. Spray bars, directional nozzles and additional circulation pumps can be used to fine-tune flow patterns. Choosing the right configuration is easier when you have access to a range of accessories, which MB Store reliably provides.

Regular maintenance is essential to keep water quality high. Plan weekly partial water changes of around 25 to 40 percent, depending on stocking density and feeding intensity. Use a gravel vacuum during water changes to remove accumulated waste from the substrate without completely disturbing the territories. Always match the temperature and basic parameters of new water to those in the tank to prevent sudden shock. Water conditioners to neutralise chlorine and heavy metals are strongly recommended, and they are readily available at MB Store in different formulations to suit tap water from various regions.

Diet, feeding routines and nutrition

In the wild, Herichthys cyanoguttatus is an opportunistic omnivore, feeding on insects, larvae, crustaceans, small fish, plant matter and detritus. In the aquarium this translates into a flexible diet, but quality and moderation are crucial. A varied, balanced menu promotes intense coloration, good growth and robust immune function while reducing the risk of digestive problems. It is highly advisable to base the diet on high-quality cichlid pellets and granules, supplemented with a mix of frozen and fresh foods.

Look for staple foods specifically formulated for large or medium cichlids. These should contain a good proportion of animal protein from sources such as fish meal or krill, but also plant components, vitamins and minerals. Products containing natural colour enhancers like spirulina and astaxanthin support the turquoise and green hues that make this species so striking. MB Store stocks a wide range of premium dry foods tailored to different cichlid species and sizes, making it straightforward to select a suitable staple diet for your Texas Cichlids.

Supplementary foods such as frozen bloodworms, krill, mysis, brine shrimp and chopped fish or shrimp flesh can be offered several times per week. They stimulate natural hunting behaviour and are usually taken with great enthusiasm. However, avoid overfeeding high-fat foods like mammalian meat or excessive amounts of oily fish, which can contribute to obesity and liver problems. Vegetable components are also useful; blanched peas, spinach or specially formulated vegetable flakes can help maintain a healthy digestive tract and prevent constipation in these large, powerful fish.

Feeding frequency should be adapted to the age and size of the fish. Juveniles can be fed small portions two to three times daily, ensuring they grow steadily without fouling the water. Adults usually do well with one or two moderate feedings per day. Offer only as much as they can consume within a few minutes, and remove any uneaten food promptly. Because Texas Cichlids are enthusiastic feeders, it is easy to give them more than they need, but long-term overfeeding leads to water quality issues and health problems. Using automatic feeders, which are also sold at MB Store, can help maintain consistent feeding schedules, especially when you are away from home.

Social behaviour and tank mates

Keeping Texas Cichlids successfully also requires careful consideration of social dynamics. These fish are territorial and can be very aggressive, particularly when defending a spawning site or when confined in too small a tank. For many aquarists, the most satisfying option is to keep either a single specimen or a well-matched pair in a species-dedicated aquarium. This allows you to observe the full range of behaviours without worrying about the safety of smaller or more peaceful tank mates.

If you wish to attempt a community setup, choose tank mates that are robust, similar in size and able to stand their ground. Other medium to large New World cichlids with comparable temperament can sometimes coexist, provided the aquarium is spacious and well structured with multiple territories. Large catfish, such as certain plecos, can work as bottom companions, but they also need hiding places to retreat from aggression. Avoid small schooling fish, slow-moving species with long fins and invertebrates, which are likely to be harassed or eaten. The key to any mixed community with Herichthys cyanoguttatus is excess space, abundant hiding spots and careful observation.

Sexing Texas Cichlids is not always straightforward, especially in young fish. Males often grow larger, with more elongated fins and a more pronounced forehead, while females are slightly smaller with a more rounded body. During spawning, however, differences become clearer. Females may display more intense belly coloration and adopt specific body postures while guarding the eggs. When forming a pair, it is usually best to allow a group of juveniles to grow together and let a natural pair form, then rehome or separate the remaining individuals to prevent constant aggression.

Breeding Texas Cichlids in the aquarium

Breeding Herichthys cyanoguttatus can be highly rewarding but also challenging due to their strong protective instincts. Once a compatible pair forms, they typically claim a territory around a flat rock, piece of slate or a carefully cleaned section of the substrate. The pair will clean this surface meticulously, often driving away all other fish with great determination. At this time their colours intensify, dark markings become more pronounced and their behaviour becomes more focused and coordinated.

Spawning usually occurs on a flat, horizontal surface. The female deposits rows of eggs, which the male then fertilises, repeating the process until several hundred eggs are laid. Parents fan the eggs with their fins to ensure good oxygenation and remove any that appear fungus-infected. Depending on temperature, the eggs hatch after two to four days, and the larvae are often moved to pre-dug pits in the substrate, where the parents continue to guard and tend them. Parental care is strong; both male and female aggressively defend the fry against any perceived threat.

Once the fry become free-swimming, they can be fed finely crushed high-quality flakes, specialised fry foods and freshly hatched brine shrimp. Growth can be rapid if water quality is maintained and adequate food is provided. It is often advisable to have a separate grow-out tank prepared in advance, along with spare filtration and heating equipment. MB Store can supply breeding cones, spawning slates, additional small aquariums and sponge filters ideal for rearing fry without exposing them to excessive current or mechanical danger.

One important consideration for hobbyists is the long-term fate of the offspring. Texas Cichlids produce large broods, and it may be difficult to find homes for all the juveniles once they reach a certain size. Responsible breeders should plan ahead, discussing potential placements with other aquarists, local shops or clubs before encouraging multiple spawns. Additionally, because this species is capable of hybridising with some closely related cichlids, it is preferable to avoid crossbreeding and to maintain pure lines, both out of respect for the species and to prevent confusion in the hobby.

Health, stress prevention and long-term care

With proper conditions, Texas Cichlids are generally hardy and long-lived. They can easily reach ten years of age or more in captivity. The main threats to their health are poor water quality, inappropriate diet, chronic stress from inadequate space or aggressive tank mates, and occasionally parasitic infections. Most common ailments, such as external parasites, bacterial infections and digestive issues, are preventable with diligent maintenance and observation.

Signs of good health include clear eyes, intact fins, vivid coloration, regular feeding behaviour and active but not frantic swimming. A healthy Texas Cichlid will display curiosity towards its surroundings, investigate new decorations and often interact with its keeper during feeding. Stress, on the other hand, may manifest as faded colours, clamped fins, erratic swimming, hiding for long periods or refusal to eat. Any sudden change in behaviour should prompt a check of water parameters, including ammonia, nitrite, nitrate, pH and temperature. Test kits and conditioners available at MB Store are valuable tools in early problem detection and correction.

When introducing new fish or making major changes in the aquarium, it is wise to use a quarantine tank. This allows you to observe newcomers for signs of disease before they enter the main display and potentially expose established inhabitants. Quarantine tanks do not need to be elaborate; a simple glass tank with a sponge filter, heater and a few hiding spots is usually sufficient. MB Store offers compact aquariums and economical filtration solutions ideal for such purposes, making preventative care much easier to implement even for hobbyists with limited space.

Long-term success with Herichthys cyanoguttatus ultimately rests on consistency. Stable conditions, regular water changes, appropriate filtration, a balanced diet and thoughtful aquarium design all contribute to the health and well-being of these impressive fish. For aquarists who enjoy observing complex social interactions, parental care and dynamic territorial behaviour, the Texas Cichlid can become a true centrepiece species and a constant source of interest.

Is the Texas Cichlid right for your aquarium?

Deciding whether to keep Herichthys cyanoguttatus involves balancing its many attractions against its specific requirements. On the positive side, this is a hardy, adaptable fish with stunning visual appeal and extraordinarily engaging behaviour. Its intelligence and interactive nature often create a close bond with the keeper; many owners describe their Texas Cichlids as underwater pets that respond to their presence, follow movements and show clear individual personalities. Observing courtship, territorial displays and parental care can be particularly captivating.

On the other hand, this species demands space, robust equipment and a willingness to manage aggression and territoriality. It is not well suited to very peaceful community aquariums or to small tanks. Prospective keepers should be prepared for rearranged substrates, occasionally uprooted plants and a need for firm, stable decorations that cannot easily be toppled. It is also important to plan for the long lifespan and potential size of the fish; they are a long-term commitment rather than a temporary addition to the aquarium.

If you are ready to dedicate an appropriately sized tank, invest in strong filtration and heating, maintain regular water changes and carefully consider tank mates, the Texas Cichlid can be an immensely rewarding species. It offers a depth of behaviour and interaction rarely matched by more passive community fish. With the help of high-quality aquaria and aquarium equipment from MB Store, along with thoughtful planning and responsible husbandry, you can provide a thriving environment for Herichthys cyanoguttatus and enjoy its remarkable presence as the true centrepiece of your home aquarium.

FAQ

How big does a Texas Cichlid get in the aquarium?
In home aquariums, Texas Cichlids typically reach around 20 to 30 centimetres in length, with males usually growing larger than females. Growth rate depends on diet, water quality and tank size. Providing ample space, strong filtration and a nutritious, varied diet helps them reach their full potential without health issues related to overcrowding or poor conditions.

Can Texas Cichlids live with other fish?
They can coexist with other robust, similarly sized cichlids or sturdy bottom dwellers, but only in spacious, well-structured tanks. Even then, aggression is common, especially during breeding. Small fish, invertebrates and delicate species are at significant risk of being bullied or eaten. Careful observation and plenty of hiding places are essential for any community setup that includes Herichthys cyanoguttatus.

What water parameters are best for Herichthys cyanoguttatus?
The species prefers slightly alkaline water with a pH between 7.0 and 8.0, medium to moderately hard conditions and temperatures from 23 to 28 degrees Celsius. Stability is more important than perfect numbers, so regular water changes, good filtration and careful monitoring with quality test kits are key. Avoid sudden fluctuations, which can stress the fish and weaken its immune system.

How often should I feed my Texas Cichlid?
Juveniles do best when fed small portions two to three times daily, supporting steady growth without overloading the filtration system. Adult fish are usually fine with one or two moderate meals each day. Offer a base of quality cichlid pellets, supplemented with frozen or fresh foods. Only provide as much as they can eat in a few minutes to prevent obesity and water pollution.

Is it difficult to breed Texas Cichlids?
Breeding itself is not particularly difficult; compatible pairs often spawn readily in good conditions. The real challenge lies in managing aggression during breeding and finding homes for the large number of fry produced. Parents are devoted and will defend their young intensely, which can create problems in community tanks. Planning and separate grow-out space are strongly recommended.
