Ugh, I dunno what to do. One of the males is being REALLY aggressive. He attacks the cherry shrimp and the other barbs. The loaches are hiding and I dunno if it's because of him. The other barbs hide in the plants. Think getting more will fix the issue? I have three at the moment since the other three died but I dunno if I should just get rid of him since he is literally terrorizing the entire tank.
