The genus Alldontichthys includes four species, which are poorly defined as yet. There is a close relationship of the Allodontichthys with the genus Ilyodon, and also with the genus Xenotaenia. The type used for the manifestation of the genus was Allodontichthys zonistius, which had previously been a member of the genus Zoogoneticus.
The name Allodontichthys originates from Greek and approximately means "a fish with different sorts of teeth".
The members of the genus are ground-oriented fish adapted to the rocky and stony beds of the fast-flowing brooks in the high country of the western slopes of the Sierra Madre Occidental in the States of Colima and Jalisco. They assimilated to their biotope with a reduction of the swimming bladder and a special design of their bodies.
These fish - except Allodontichthys tamazulae - do not tolerate temperatures over 22 Â°C over a long period of time.
The males live strictly territorially. Since the fish can sometimes kill themselves in ranking fights, it is absolutely necessary to keep them in pairs in large aquariums. Sufficient hiding places should be provided in the form of luxurious vegetation, stones and roots. Because of the aggressiveness of the fish, breeding is not simple and requires space. The nutrition of the fish is without problems in contrast.
