Fish stocking depends on what your filtration is like, how many, how big is their max size, and also temperament
I can jam pack my 125 with fish (fish list on my 125 gal thread), but I have 3 high power canister filters
Size, number and temperament :
you can put maybe 2 pairs of Apistos in that 55 without anything else in there or you can put some 40 cardinals. The apistos will argue and torment its tankmates during breeding season, while cardinals wont harm anything (shrimp maybe ?)
Pencilfish needs to be kept in a group, I have heard more than once than a lone pencilfish can go beserk and terrorize the whole tank.
