I have a 240l aquarium with 2 jewel cichlids. They share the tank with gourami, tetras, plec, clown loach and panda corys. I noticed recently one of the cichlids had started hiding behind the filter and the other frequently chased this one. I know I either have to add more cichlids or separate them into multiple tanks. I have a 100l tank, not presently in use, but it’s not big enough for another shoal of cichlids, and I don’t really want to move the community, which seems very settled (I have been building the community for 2.5 years). I am assuming the cichlids haven’t paired, hence the problems I’m now noticing. The cichlids are now a good 5 inches and beautiful jewel cichlids. Any ideas on what I should do. ( I have got caves, driftwood and some plants in the tank).
