belly crawlers actually get closer to 10". if your gonna do a small aggressive community than stick with some thing in the wallicis. like a couple reganis or a couple compressiceps. than you can add some dwarf cichlids and maybe some barbs or something.HerCrenVie;1273350; said:Belly-crawlers get to about 7". I don't know about their aggression levels, but I'm 100% sure you can keep a bonded pair in a 55g. Take note of the word in bold.
