Cleithracara: Greek, kleithro = to close + tupí guaraní, Acará, the name of a fish in Amazonas river maronii: Named for its type locality, the Maroni River.
Keyhole cichlids have been popular in the fish keeping hobby for many decades due to their mostly peaceful and slightly shy disposition. They are very peaceful even with smaller fish apart from when they are breeding. Even when breeding the other tank occupants will only be excluded from the immediate spawning site.
Wild keyhole cichlids enjoy a diet of worms, insects and crustaceans. Try to replicate this diet by offering similar items either live or frozen. In addition to these items keyhole cichlids will take flake food and suitably sized pelleted food. They are generally quite bold feeders and easy to please.
Keyhole cichlids are usually very peaceful except when breeding at which time they will defend their territory against all other fish.
The gender of juvenile keyhole cichlids cannot be reliably accessed. But when adult the male keyhole cichlid develops longer and more pointed anal and dorsal fins.
Breeding Cleithracara maronii is very easy. If several juvenile fish are raised together they will eventually form in to pairs on their own accord as they mature. They will select a territory and begin breeding with no special treatment but the chances of any fish being raised in a community tank are very slim even with parental care.
Wild populations of Cleithracara maronii have not been evaluated in the wild. But almost all the fish offered for sale within the aquatic trade will have been commercially bred.
If frightened or startled a rapid change in colour to a more mottled pattern will be noticed.
