Thanks guys, for all your replies.
I have not seen them do anything to the 2 pajamas, 1 algea blenny, 1 watchman gobie, 1 large brittlestar, or grren mandarin. in a 45g tank.
They seem to know they are in a tank where they dont exactly " Fit in " and avoid contact with the corals that have long tentacles.
They maybe sneaking a hermit crab down for lunch here and there, Although I have never seen it, but i havent noticed a crab or snail population drop or any adverse affect of having them in my reef tank..
Lotsa inverts, dusters and stuff .. I would not put any shrimp in with them though.
And if you know green spotted puffers... These guys are very happy and healthy.
( White bellies, light green patches on there heads and blue/green eyecolor.)
