There is a possibility I have overstocked my 120l tank (posted as a seperate post). If so I'm thinking of restarting it. I became quite interested in Discus recently and was wondering how many I could keep in a 120l tank. My tank is rectangular bow shaped tank with good height. And what are suitable tank mates for discus? I quite like a specific eel which I can't remember what they're called but it seemed friendly and a fairly docile creature. I also like bettas (but obviously 1), tetras and black ghost knife fish.
Thanks!
Thanks!
