My Maroon Clown (RIP Stripe) was a Pit Bull! He'd bite and hang on! I accidentally tossed him out of the tank more than one time just because when he nipped I pulled back and Stripe would be bouncing on my desk here in the office. Very troubling LOL!
My starry blenny "Sigmund" (aka Sig) is the biggest chicken I've ever seen only to be out-done by my purple reef lobster. I think he goes to hide when I simply blink in the same room he's in LOL!
