I have a 1.5 gallon tank with an algae problem. I clean the tank twice a week but try to avoid doing HUGE water changes and scrubbing every inch so I don't stress my old guy out. He's over 3 years old but still very happy.
I also have a 10 gallon tank that has a problem with snails. Do snails eat algae? If I put one small snail into my betta's tank would that be a good idea? He's pretty laid back so I think he would poke at it once or twice then leave it alone.
