Hello all! I am new to this forum thing. I am almost embarassed to post something because I might be doing it wrong. I just switched from a 20 gallon tank with my 5 african cichlids (who grew so fast) to a new tank which is a 55 gallon. They have been set up in the 55 for about 3 weeks now. I inherited a few more from a friend whos tank leaked and now have a pack of 12 in my 55 gallon. I have two of what I thought were blue frontosas. They were both really gorgeous dark blue with dark black stripes. One of them is turning colors though and I dont know if its a good thing. He/She started to fade to a lighter blue color, and then to an almost white. Stayed white for about a week and only blued up when I fed her/him. Started getting very territorial and staying in one of the logs i have in there and when anyone comes near her log she runs them off. She is not white anymore now she has almost turned to a bright yellow. I don't understand. She/He acts healthy and this has been going on for about 4 weeks. Any suggestions?
