I had purchased a new frogfish last thursday. He looked pretty good at the lfs. I noticed that he looked kind of fat when he was bagged but I shrugged it of to a full belly. He basically diapeared into the reef until today. I finally saw him coming out of the rock work and he looked really bloated. His breathing was pretty rapid and he seemed pretty slugish. Tonight when I was checking out the tank he was on his side and his mouth was gaping. I got out the net and kind of nudged but it was to late. Is this a normal malady for a frog? My tank is in great shape and we acclimated with dripping for 2 hours. I am sure he must have brought whatever killed him with him. What the heck happened?
