Hi, I got 3 fish as a present. I'd like to ask which fish I can give them with. I have 2 options and that is to malawi mbuna cichlids, but i am worried about them biting their fins. And the other option is to a community tank with tetras, but here I am afraid they will eat the small tetras. Which option is better? Or would it be better to try to return/sell the fish.
