Welcome to the board.
Heh, the barbs are always active
It seems that our guy manages to gobble half of the ration of the entire tank. He is one chubby fish, but as soon as food is in he is torpedo fast.
I'd say if you don't find your question only partially answered then do post clarification to followup. I personally don't mind new threads that go "hi, I know that X and Y, I'm trying to wrap my hand around Z and here are my doubts." . Shows you did research. Can't promise I'm competent enough to answer though
