Neoophorus HUBBS & TURNER, 1937 The genus Allotoca includes five species. Altogether, not very much is known about this genus. Unfortunately because of the progressing environmental pollution in Mexico some species are probably heading towards extinction. As aquarium fish the demands of the individual species seem to differ to some extent. Whereas the occasionally kept and bred species Allotoca diazi is quite durable and aggressive and therefore needs its own roomy tanks, Allotoca dugesii on the other hand can be kept in sufficiently large community tanks with other species. Only meager information is available about the other species. These fish temporarily tolerate temperatures up to 24 °C. Nevertheless, some variation in temperature during day and night (and even more important: variation through the year) is important for the health of the fish. The water-temperature should vary between 16 °C and 22°C. Breeding for several generations is still a difficult problem that might be caused by constant too high of water temperatures.
