I have observed that other cichlids at the sight of the guarding male just change subtly their route to avoid the nest vicinity, any careless fish that comes too close is then chased away by the angry male. Cichla is another genus of cichlid. Plant life is found in some rivers in the form of large weeds that the fish use for cover Rio Amacuzacbut mostly no aquatic plants are found in the main courses of the rivers where istlanum lives.

It is important to state that, as for other Central American cichlids, Istlanum is just found in parts of the rivers with a maximum altitude of meters above sea level and then just in those waters that are not too cool for them.

Of course these fish need large tanks and an equipment that fits their needs, but if these things are given any aquarist will for sure enjoy keeping them. Gourami Swami likes cichlasomz.

At that point the generic status of istlanum as well as that of around a hundred of other Central American cichlid species placed in that genus was left in the air. My observations on ‘Cichlasoma’ istlanum show that they are usually a shy cichlaso,a fish moving close to the river floor in small groups among the banks, stopping once in a while to shovel their mouths several times in the sandy or muddy bottoms to get a mouthful of substrate that they filter in search for any edible matter, proceeding afterwards to spit the rest back to the substrate.

Wrigglers become free swimming and at this point they abandon the nest for good, both parents staying close to guide them through the shallow and quiet waters of the river to graze for food, mainly the male showing the route with the typical ‘Cichlasoma’ spasmodic movements of his fins and the female staying close to the heart of the fry cloud. We now have this beautiful fish in istlaunm.


Nevertheless, the absence of natural geographical accidents like waterfalls in the lower rivers leaves a very large uninterrupted range for Istlanum, much larger than the majority cicchlasoma the ranges known for Central American cichlids. I had a big rebular pair and a smaller tangerine pair from Conkel. The Grotto Last Seen: I bred them both several times, but males killed both females and the fry are viscious to each other.

Highly respected and experienced aquarist, Pam has visited cichlid habitats around the world, and bred in her’s and her husband Gary fish house hundreds of cichlid species. The bigger danger this beautiful cichlid faces is as usual of human origin; introduction of exotic species, both for food or amusing purposes plus the careless pouring of wastes in the river courses, are some acts that pose a risk to all freshwater fish populations in the world.
