Cichlasoma cyanoguttatum (texas cichlid)  

The Texas cichlid is a very common cichlid which combines two of the characteristics that make it a good choice for those interested in New World cichlids. It has the typical behavior of these species but doesn't grow very large which makes it an option for hobbyists with smallish tanks. This fish is found in Texas rivers and lakes and it is the Northern most cichlid. This means that the tank temperature should be set a bit lower (20-24 C) while in winter it can tolerate as low as 15 C without any problem. Territorial and aggressive it requires a tank with rocks and wood where it can hide while it is a good idea to define territories in the tank (with rocks etc) to avoid fights. Fine sand can be used as the gravel. It is almost impossible to sex this fish. The fish may reach an adult size between 12 and 30 cm. The pH is not critical - it should be around 7 (a bit alkaline is preferable) and the GH could be anything from soft to medium hard. Will eat anything from commercially available foods to live mosquito larvae, tubifex worms, spinach and lettuce. As with all New World cichlids, the filtration system should be strong enough to cope with this fish.
