Wrasse's are pretty good with alot a flow. But that doesn't seem like a lot of flow to me. I had 2 seio 1100's, 1 KORALIA 3, 1 MODDED mj 900 and my eheim 6012 (I think). I had 2 wrasses, 2 percs, and and algae blennie. Clowns aren't cery good swimmers to begin with but they can do ok with the flow.
