Hi All..just was curious if anyone has some insite on something my sixline wrasse has been doing occasionally. Bascially he will swim with his body vertical backwards for a bit then move vertically down the tank and quickly flip his tail(back half) and swim normally. When he does this its always in the front viewing area of the tank and he kicks up a little sand below him. Almost seems like he is playing in the current, fish dosent display any ill symptoms. Could this just be him having fun? I've only seen it maybe 3 times in past couple months. good healthy tank, 60 gal, live rock and all that. I know he isnt being hasseled by any other fish. Just thought it was kinda strange.
