a very shy fish , you will rarely see it . i have one and for the first month i never saw it in fact i thought it had died but my aquarium has many caves for it to hide in.
In Quarantine it wouldnt eat any pellets but i saw it eating micro algae and nipping at zoanthids in my tank , If there are alot of corals , the nipping maybe dispersed a bit. Not an easy fish to get to feed prepared food but is possible mine is eating chopped mussel now.
Here is a pic of it before it went into Q , lovely fish in the light!
