OK..my lfs had some arrow crabs that the kids love to watch. They said that they are safe, don't eat fish, don't eat snails, just eat stuff in the rock/ground. They were in fact living in a tank with some peppermint shrimp (many actually), other types of crabs and some small fish (I think blennies).

So i got one, but it in the tank last night, then started reading around a bit... some say they are bad crabs, can sometimes get hungry and catch a fish, others say they are fine. I have some tiny featherdusters that we like looking at, and sounds like they will eat these...

Should i return the arrow crab? Or should I "wait and see"???
