So I have had a a community of African Cichlids for awhile now . A month ago I found one of my OB red zebras was being attacked badly so I pulled him and he has since been in a 20g long. Now about two weeks ago I found a Kenyi being attacked and singled out, so pulled her out (weirdest thing though once pulled out and put into another tank she / he now lol decided to show his egg spots and started changing greenish yellow (not full yellow yet). Well now back to the point, yesterday I found yet another Kenyi Female ( for sure female she has had a batch or two), being attacked and singled out. So I know they do get more aggressive as the get older, but just seems like they are singling a single weeker tank mate out. They have all been peacefully for the last 6 months or more. I even upgraded from 55g to 75g back in october. They have tons of hiding spots I have tons of rocks and cave areas set up. I am just concerned I am going to keep pulling fish out till I am left with very little. Any suggestions would be great. I guess I need to figure out who is doing the most attacking. Plus is there any point in putting the Ob zebra back in, his wounds have pretty well healed and fins are in good shape again?
