How is the temperature of your water? Sounds like it could be chilling....check to make sure it's not too cold.

LionFish says.....
Well, the thing I would check first would be, like goldfish said, the temperature. What do you keep it at? They prefer between 77 degrees and 82 degrees although, I keep mine at 78. Have you had any new additions to the tank recently? Anything at all? My lions did that when they were new but they haven't done it since.

My temp in the water is 80 degrees.I have but in a puffer for about 2 weeks.I talked to some other saltwater freinds and they said that i shall kill him and take him out of the water becuse hes not going to make it,is that true??

 

[goldfish]

Maybe he is upset by your puffer being added? Its a bit strange since lions are pretty well able to handle most aggressive fish. I wouldn't take him out of there quite yet--where would you take him anyways? The stress of moving him from place to place is enough to kill him. I'd leave him alone for now and keep an eye on him. Hope it helps!!
