this thing rocks. it is so cool looking. i wanted something so my clowns would stop living in my hammer coral even though it is cute. got this guy from a local reefer for 50 bucks. pretty good deal i think. it is about the size of a softball. my female clown has been paying alot of attention to it but hasnt gone in to test it out yet and it has only been in the tank for a day so hopefully they pack there bags and move soon.
