What fish/inverts can go with a picasso trigger? I recently had a problem with my trigger and he is being moved to my other tank and all the two fish in that tank are being switched to the tank he came from...but one fish in this tank will be boring...i don't intend to do the switch for a bit, I'm actually trading with my dad but he wants to know what can go with it and have some options before he gets stuck with fish that doesn't play well with others
