I've had my tank set up 50 different ways and had mbunas for over 2 yrs they are finally nippers and very obnoxious little fish compared to peacocks, but to answer this post question, that is a very nice setup for your peacocks, I'm jealous... Can't find no flamebacks around here and I don't like ordering fish, my guy who owns Milwaukee aquatics usually orders for me and now I have to get me some flameback3
