I have a 55-gallon Semi African cichlid tank. That is they are all Africans except the opaline gourami, the 4 yoyo loaches, and the green spotted puffer. Here is my issue. The red zebra is picking on everyone. Is there anyway to diffuse the aggression because i feel bad for the other fish. All of them are less than 3 inches. In total there are 11 fish. I have heard that you can overcrowd a bit and it will get rid of a little aggression, but how many fish would I need to do that? So far the other fish are stuck in the corners and the zebra sits in the middle of the tank waiting until someone moves. I think that i should have enough places for them to hid, but the pesky zebra finds them and runns them out. Am i doomed, am i going to have to pick a few and sell the rest?
