My experience is just like yukonblizzard's. I frequently sing the praises of these fish. I think that foxfaces (of the vulpinus/lo and magnifica species, not to mention other rabbits) are excellent aquarium fish, and quite underrated. Mine has never nibbled a single coral, and singlehandedly eradicated the hair algae issue I was having for awhile. It has never bothered another tank inhabitant that I've seen. They are relatively inexpensive (even the maginificas can generally be had for around $100 or less) and very hardy. They have an exotic shape, and the "camo" mode is interesting to observe. The fact that they are venomous is really their only drawback (I always use reef gloves when I put my hands in my tank, and that's not only a hassle, you can't have much precision - it's practically like wearing mittens.). Although that same feature also allows them to be kept with some pretty aggressive fish, if you want.
