I recently got a pair of cockatoo cichlids for my 20 gallon long. I already had one male kribensis in there. So far it’s been a couple of days and they’re doing fine. The krib will occasionally chase the cockatoos but never really bite them. The tank has plenty of cover and caves but I was wondering if keeping the two species together will be a problem in the future? The krib is fully grown I believe and the cockatoos are both juveniles.
