General Notes:

Uaru fernandezyepezi are generally very peaceful with other peaceful fish of a similar size. they will however wreck plants so can't be housed in a planted tank. Due to the soft acidic water and high temp required by these fish any tank mates need to be carefully chosen. Uaru fernandezyepezi can be kept in a group although they will probably become more aggressive when breeding. They can be delicate if not kept in the right conditions and they are prone to hole in the head disease in less than perfect conditions.


Wild Uaru fernandezyepezi are herbivores in captivity they are unfussy and will accepts most foods. In order to thrive they should be fed on a vegetable-based flake or pellet food, plus occasional fresh or frozen foods.


There are no external differences between the sexes.


Uaru fernandezyepezi is rare in the hobby and breeding them in captivity is even rarer. They have been bred and breed in typical cichlid fashion with both parents caring for the brood.
