green carpet nem

[t5Nitro]

I'm at a store andthey have a nice colored green nem. I'd like to buy it for my Picasso clowns. Do green carpets have a record of eating other fish or anything? It's around 4" and 40$. I have a yellow tang/foxface/bangaii cardinals. Any problems with fish load? I use metal halide lights. Anything else to know?

I am going to assume that it is a Haddoni, which others have had an issue with eating fish. (( In the 9+ years of keeping Haddonis, I currently have 4, I have only lost 2 fish to them )).

Is its mouth tightly closed?
