Basically a buck toothed cleaner wrasse that swims and acts a tad more aggressive at the "cleaning" station.lol

Funny, I read about these in a book as a child (some of you may argue i still am a child) and thought they were the coolest thing. I would love to have one but I can't imagine the stress it would induce. Nature and evolution are such marvelous things.

 

they also handle transport extreamly poorly in my experience. evolved is absolutely right,mine does occasionaly chase my toby around and I cant imagine its pleasent for him but they are otherwise both doing well. he seems to prefer cleaning my yellow belly blue tang and my yellow tang. but will at times cleans the smaller fish too.
