Hay all tomorrow i'll be purchasing a Potomotygon Motoro and try to get some tank mates for him/her. I'm planing to purchase some Polypterus senegalus (2). The ray will be between 4-5 inches disc which is just a baby, and the senegalus will be around 4-5 inches will they nip eachother at this size? I don't know any other tank mates right now any suggestions will be great.
apparently it's all bichir dependent...
