Ive always had fish that could breath at the waters surface to get oxygen, but now that Ive got a 10 gallon community tank I want to be able to have other fish in it. I have a hang on the back type of filter but the water level is higher than that of the outflow on the filter. Thus, the current goes under the water withought falling ontop of it; im not getting tiny bubbles in the water. Is this ok for my non surface breathing fish? or do I need to lower the water level to get the bubbles?
