Food and feeding

Cichla monoculus are carnivorous and will see smaller tank mates as food. They can be fed on live foods or frozen foods but should accept quality pellets after a time.


South America; Cichla monoculus are to be found in the Amazonian Basins of Peru, Colombia, and Brazil.


There are no visible differences between the sexes but it is believed that the males will mature months before the females. Some males may develop a nuchal hump


Cichla monoculus grow very large, a large aquarium or pond is needed for breeding purposes. The eggs will be laid on a flat surface and both parents will protect the batch. They will continue protecting the young for a few weeks but when they are ready to spawn again, it is best to remove the fry for their own safety. The fry are quite quick growing and will thrive on brine shrimp and crushed cichlid pellets.


It is believed that Cichla monoculus can live up to 20 years.

Short description

Many keepers will keep Cichla monoculus in ponds as they do grow very large.
