Ok so my mom has a 10 gal tank that has bad algae problems and she is wanting to make it just a beta tank. Her other tank does fine on algae because of a very gentle and happy CAE. But she's been asking around and thought about getting some otos for the 10 but I think she wouldn't have enough room even with just a beta. IDK- and I'm hearing that the otos almost always die in a month because they starve or whatnot. But she always puts algae wafers in for her CAE and corys and mollies in other tank. what do you think? Any ideas?
