I got a Lawnmower Blennie last Sat. 7. He was very active in the bag during acclimation (1 hr) and seemed to want out bad. When he went in the tank he hid by the overflows for the rest of the afternoon and the next day. I have not seen him since Sunday. I know he is in the rock work some where, and he has plenty around to eat.

How long will he stay hiding? I have another fish (gobie) that likes to hide, sometimes he is gone for over 2 days.
