Am I the only one who gets attacked by my Clown when sticking my hand in the tank to do routine maintenance? The little guy flies around my hand like a shark, and nips at me. He/her actually got in between my fingers and got ahold of loose skin, and bit hard enough to leave a red mark. Are Clowns always that aggressive? Or is mine an exception? I can even try and shoo it away, and he is like a yo-yo, he just comes right back after me. It is kind of comical to watch, but a pita when I always have to watch my back.
