Looking for info on this cool starfish...

[ScubaSteve]

This isn't my usual style but yesterday I bought a starfish with only an approximate guess on the species and a gut feeling. Normally I research the heck out of things before they go in my tank but this guy was too cool to pass up and, well, I'm up for a little challenge (see pics from net below).

I've so far been able to ID it as Neoferdina sp., most likely N. offreti. Turns out they're fairly uncommon and more so in the aquarium trade, hence the lack of information readily available. I'm trying to find info on this guy as to his behavior and diet. I'm expecting someone to come back saying "Will eat every living thing in your tank" but based on his physical traits I have a feeling that he'll be somewhat similar to Fromia sp.

Anyone out there able to give a hand on this one?
