I have a 6yr old polypterus about 14". Recently lost his tank mates due to old age. (Had 3 bala sharks that were about 10yrs old with him. Lost the first about 6months ago and the last about a week ago) Gladiator has a fabulous personality. He follows me as I walk across the room and stares at me with his mouth open when he thinks he needs to be fed. Since the loss of his last tank mate he turns to face the back of the tank whenever I get close. He's still eating but doesn't stare me down for food anymore and waits for me to leave the room before he'll eat. I have seriously angered my fish. Lol. I need to get him some new tank mates, but I'm at a loss as to what I can get that's affordable, like the $10-20 range. Needs to be big enough he can't eat them and not aggressive so they don't torment him. Any ideas?
Thanks
