Hello I have a 40 gallon tank. I have a 750 gph
coralvue powerhead. However I dont think my clownfish like it. I have it right near the surface so it makes a lot of ripples for oxygen. But my clownfish always hide behind it, acting like they dont like the current. Should I readjust my angle so they are more comfortable? They are quite small still. The biggest one is about 1.25 in and the smaller one is 1 in. Why are they always hiding behind the powerhead?
