I was watching my aquarium 8O after I added a new set of fish (threadfin rainbowfish). I noticed one of the fish was incredibly smaller than the rest I shook it off and concluded that he was gunna grow. HE HASN'T!
. I was wonderin' wat is up with him. He eats frozen bloodworm, live brine shrimp, live daphnia and flake not including the dried foods I provide. My aquarium has two 10percent changes in a week has no diseases and is very healthy. Is he just a 'runt' and is that a bad thing? Or is there anything wrong with him? (bearing in mind he isn't gettin' smaller and he isn't 'bullied' by any fish either)
