Distribution and habitat
The distribution area of the two-striped cichlids is southern Mexico and Guatemala, where they occur in the catchment area of the Rio Usumacinta and the Rio Grijalva. They live mainly in stagnant river sections, lakes and lagoons, with dense aquatic vegetation
Maintenance
The aquarium should have a dense border planting, with many hiding places (stones, roots), and offer free swimming space. A substrate of sand covered with some foliage (e.g. sea almond leaves) and shaded light (floating plants) is ideal.
No ammonia, ammonium and nitrite should be detectable, the nitrate value should not exceed 100 mg/l. To ensure water quality and oxygen content, a filter and heater adapted to the size of the aquarium is required, as well as lighting for the species-appropriate day-night rhythm of the animals.
Diet
The food supply consists of high-quality dry food for cichlids (pellets, granules), supplemented with some live or frozen food, such as artemia, mysis, shrimps and red mosquito larvae or a commercially available, frozen special food mix for cichlids. Furthermore, they need sufficient vegetable food, such as spinach, crushed peas, algae leaves or dry food with high vegetable content (spirulina).
Only feed as much as will be eaten within a few minutes. A regular and varied diet promotes health and increases resistance.
Behaviour and compatibility
They are very temperamental fish that should be kept in pairs. During the spawning season they behave territorially and defend their territory emphatically. They often behave aggressively internally. Group keeping is only recommended in a much larger, richly structured tank. They can be socialized with other robust Central American cichlids. They regard too small fish as food
Basically only compatible fish species with similar demands on water condition and water temperature should be socialized.
Sex dimorphism
The sexes are difficult to distinguish. Adult males are more colorful and have slightly longer extended dorsal and anal fins
Reproduction and breeding
They spawn on shallow stones or roots (open brooders). Both parents perform brood care and intensively defend the territory (parental family). After 2-3 days the fry hatch, which are then housed and guarded in a prepared bottom pit until they swim freely after 4-5 days and the brood care ends
Fry must be fed several times a day with special rearing food (e.g. Artemia nauplii). In community tanks breeding is hardly possible, because the fry are easy prey.
Important
There are a few site variants that differ in coloration.
They like to burrow, accordingly, stone structures must be very stable. Plants should be placed in heavy pots and secured with stones against burrowing.
Foliage (sea almond, oak, etc.) enriches the water with humic substances, naturally lowers the pH and is a valuable secondary food source (detritus)
The well-being of the fish should be monitored regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least every 14 days. Regular partial water changes are recommended, even if the contaminant level has not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
