Hi, I'm new here and have a question. I have bala sharks in with some of my South American cichlids and I have noticed that a couple of the balas have been rubbing on each other. I'm thinking they are trying to breed but I have never dealt with this. I left the balas in that tank and moved the cichlids to another. Am I doing the right thing here? And how long until I know if she's going to have babies? my bala Sharks are rubbing up on each other like they're trying mate but I have read that it's impossible to breed bala Sharks in an aquarium. Help.
