|Ameca splendens male|
Species which evolve an ecology based around production of comparatively small numbers of young tend to have limited dispersal ability, and as a result the killifish, both the egg-laying and live-bearing forms, tend to develop many endemic species. In the highlands of Mexico, where mountains have resulted in numerous small watercourses, this has resulted in large numbers of species with limited ranges. Unfortunately, agricultural development, deforestation, and introduced species such as trout can have a devastating effect on these small water bodies and their unique inhabitants, so many species of Goodeid are classed as threatened or worse.
Not all the species we have are on show, but among those in the display tank (which are producing young regularly), are these:
Ameca Splendens Butterfly Goodeid
Ataenobius toweri: Bluetail goodea
Characodon lateralis Rainbow characodon
