Now I might receive a bit of flaming if this is a bad idea, but could I keep a wartskin or some other type of anglerfish in a 45 gallon tank? I know corals aren't an issue and the only things that i think would be a risk of being eaten are a 3" or so mandarin dragonet, 4.5" decorated goby, 2" maroon clownfish, and a 3" dwarf lionfish. Please don't complain about if some of the other things are bad to keep with eachother, as I've never had a single problem, and the most agressive thing in the tank would probably be my filter feeding sea cucumber, which viciously ate silversides yesterday. (WTF??)
