Well I have a lunare wrasse and it killed my small porc puffer by realizing he could make him puff up. Well I am playing with the idea of trading him for a puffer (prefer something decent sized) if anyone is up for the idea that lives in the denvaer area I don't want to mess w/shipping or anything. My wrasse is about 8" and is very healthy and active during the day it is nonstop movement and at night it sleeps once the lights go out and can't be found in the rock work.
