Hi, I was just reading the post about an octo in a classroom and Jean had said something about air bubbles in an octo tank. I just recently got an octo and am worried that the bubbles in my tank might kill him. I do not have any air stones, but my filter (Fluval 4Plus) gives off LOTS of tiny bubbles into the water as it puts the filtered water back into the tank. Is this bad? If it is, how else am I suppose to oxygenate the tank?
