Keeping other fish with them is tricky as they can swallow something almost twice their size. So you would need a fish that would stay somewhat larger than the angler. Some fish will mistake some of the frogfish as food and can injure it picking at it.

Snails and hermits are okay with them but shrimp and crabs like sally lights or emeralds will be on the menu.

I've never had any problem with corals unless the prey gets into the coral and then it might get nipped as the angler nabs the food. They can irritate corals by sitting on them, but you can run them off of the corals a few times and they generally learn not to go back to that spot.

As to special requirements you need to be careful feeding as to not overfeed. Since their digestion is slow, overfeeding can lead to food decaying in the fish before digestion injuring orkilling the fish.

Work at weening the angler off of live food. Mine took to feeding off of a feeding stick very quickly, some never accept anything but live food. I gut load live feeder fish and ghost shrimp with cyclopeeze prior to feeding them to the angler.

The only time mine has ever struck at my hand is when I've been scooting him around the tank to get at something he was setting on. It didn't hurt, just kind of startling how fast he can move when he wants.

When moving the angler from one tank to another do your best not to expose it to the air as they can gulp air and get a bad bubble in thier gut.

That is all I can think of off the top of my head, let me know if there is anything else I can help you with.
