I have a clown fish that hides (hosts) a group of rocks and the inflow of the protein skimmer. At night when the lights are off he tends to hover to the top above the inflow of the protein skimmer, which causes him to be in close to the top. Sometimes goes a little sideways. At first I panicked and checked the water, but everything came back normal. SOOOOO, does anyone have a clownfish that does this? Hovers close to the top? \n \n Maybe he is hosting the protein skimmer … I don’t know, but it’s kinda funny if he is.
