Dogface puffer acting strange ??

[jarrid]

My new dogface puffed is acting what I would call strange. I have seen him numerous times during the day sitting wedged in the live rock and he is darker than usual, like he's sleeping. When I put food in he usually comes out right away and eats then when he's full he goes back into the live rock. He is the largest fish in the tank and has three triggers and a small snowflake eel as tankmates along w a frog fish. I have never seen any of the fish even try to harass him and don't know what to think. Is he just sleeping ? Are dogface puffers normally lazy ????
