I have a 54G Bowfront corner tank and I have read that you should put less fish in them than say a "normal" 55G rectangle tank, but I can't find anywhere that says how much less. This is what I currently have in the tank
1 Cutteri 2"
1 Keyhole 2"
1 Buffalo Head 2.5"
1 Rainbow 2"
6 Danios for them to chase around.
My question is should I stick with just these, will this be too much fish when they reach adult size or can I add another similar sized cichlid to the mix?
