Frogfish maybe swallowed air?

How much are you feeding him?

When I first read up on frog fish, a very specific warning was included to not over feed them or else the built up digestion gasses will cause them to float, sometimes to the point of death.

Unfortunately Michael doesn't have a whole lot on this problem in his book.

From Scott Michael's Reef Fishes Vol 1 page 338
"Frogfishes have the potentially suicidal habit of ingesting air, especially during shipping or when they are lifted from the water. For this reason, it is extremely important to keep them submerged. If you need to transfer an individual from one tank to another, use a specimen container not a net to catch and move it. If they are being transported from the store to your home, the water and the frogfish should be carefully poured from the specimen container into a plastic fish bag. When you get home, acclimate the fish, discard some of the water in the bag, then submerge the bag opening and release the frogfish into the aquarium. Although I usually do not recommend adding water from a dealer's aquarium to your own, in this case of a frogfish it is warranted. If your frogfish ingests air during the transfer, there is not much you can do. They will often succeed in expelling the air on their own, but it is not uncommon for specimens to float around until they die."
