i wanna add some schooler to my 29g growout that currently has a b-fly, L-200, 3 tiny ottos(temp clean up crew and bichir food), and an 4" ornate.i was thinking bout tiger barbs, mabe 6, do you think they would nip the b-fly in this big a school? i dont mind if the bichir eats them cuz its his tank and they're only a dolar, im just worried about overstocking and the b-fly fins.
