I'm looking into getting one of these too so I'll tell you what I've found. They're relatively new to the hobby as in they haven't been collected much before. They seem to hide a lot, especially during the day, so if you want a fish that will be out in the open I don't reccomend getting this one. I've heard conflicting reports on what they eat, everything from crustaceans to hair algae, hopefully someone else can help clarify this. If you want to research it more, try searching for the scientific name Priolepis nocturna because they go by many different common names.
