Have a 210 tall tank, I have a single male dovii in the tank that is 4.5 inches. I wanted to know if a powerhead is beneficial or not. I already have the powerhead setup just don’t have it on, I have a FX6, FX4 and aquaclear 110 for filtration, the 110 seems to aerate the tank pretty well. Not sure how much current the dovii’s like.
