Clownfish tail split?

[Vinniejt76]

I noticed today my clownfish's tail is split, just like someone cut it with a pair of scissors. Is this a symptom of something? He looks and acts completely normal otherwise.

I wouldn't worry about it unless you observe other symptoms like heavy breathing, cloudy/opaque areas, or fuzzy growths.

My 6 line wrasse used to attack my clownfish. His fins would split like that, then heal up just fine. It kept happening so the 6 line went bye bye.
