Is it possible to keep a healthy population of endlers with a larger fish that would eat them such as a firemouthcichlid? Say the endlers would breed as fast as the cichlids can eat them they would be able to sustain themselves?
Well, that depends on how those cichlids will react, of course. The simple answer on this question is "yes"! But if it will work out wel or devastating, is another story...
I do keep certain endlers also with some predators, but in some way, those predators ain't interested in them.
If you're not sure but you'd like to proceed, be sure to have sufficient hiding spots for those endlers. Or just keep them in seperate tanks.
