i had three fox faces at different times, and i've also had a rabbit fish at the same time as one of those fox faces, lovely fish. so pretty, i love how they camouflage with the rock while they sleep. it use to be really hard to find it. the two bigger ones i had were never scared when i would walk around, but the 3rd one i had was about an inch and a half and it would never come out when i was around, if by chance he was out and i walked in the room it would dash into the rocks, after a while i just got tired of it and traded it into my LFS. i was weary of getting another one because i read "reef safe with caution" on live aquaria. but i think i might just give it another shot because they are really stunning.
