I have 5 africans in my 55g and my slender mbuna chases my bumblebee cichlid to his corner all the time. he doesnt bother anyone else, in fact the other ones swim with him. Should i take the bumblebee back? I really like the slender mbuna so i dont think i will take him back. Well my tank is also kinda bare right now, i still gotta pill some rocks up. Where is a ggod place to get rocks for this tank and how much do they cost?
