just a quick question.
in out tank we now have 1 x oscar, 1 x flower horn, 1 x pleco, 1 x pepper catfish and 2 x tin foil barbs.
why does the oscar ONLY attack the flower horn and pleco? he seems to leave our cat fish, even tho he'll be able to fit into his mouth, and our tin foil barbs alone
cheers
