There have been lots of Huma questions lately. They're beautiful and personable fish. They seem to be plentiful and inexpensive. But, no matter what size, these are aggressive triggers and can go from nice to monster overnight. Most triggers will chomp anything that even appears edible. IMO, the only triggers I would consider "reef safe" are the blue jaw (blue chin) and very pricey crosshatch. Others have worked, but there exceptions to everything. I think it would be hard to find an experienced reef-keeper who would take a chance with his beautiful tank, by introducing any trigger. (Except, maybe, a blue jaw.) Also, if you're doing a FOWLR, I wouldn't keep the Huma with any lionfish.
