Ok, Anglers...Most anglers that are available on LFS are either sargassum fish, Gigant frogfish or A. Striatus, (unless you get it special order) most available here in S.A get a large size, so you need a large tank. i would not suggest you put anything else with an angler, they fit anything they can in their expandable jaws. Since you need to monitor what they eat and how much they eat, you must not have any other fish nearby, since he will eat them and the excess off food can rot in their stomachs and kill the angler. One of the anglers natrual pray are lionfish, the venomous spines dont matter, he'll eat it anyways. Anglers like to perch and walk around, i would not suggest an anemone, since they may sting it and therefor kill it. So if you want to start an angler tank, remember he must be there by himself or in male/female pairs, which is very hard in captivity but its doable...HTH's
