arrow crabs

[mollusk3D]

Im currently cycling a 20 with about 35 lbs of lr and am trying to decide on occupents. i definatly want a pair of false perc clowns and a neon goby and im still un sure of a cleanup crew and eventually corals (mostly zoos and shrooms) and i was wondering if an arrow crab could live peacefully with these guys. they have one at the lfs with corals and clowns but you know how fish stores can be.
thanx

my arrow crab ate one of my shrimp so you may want to think about the future if you want a shrimp. also the arrow crabs are very sensitive to salinity shock. I shocked my arrow crab when I was poring in water during a water change. I didnt realize it was right where the new water was going in. he "passed out" and rolled down the rock to the sand where a different shrinp came out and ate the arrow crab. also, they can get big. the small ones are "cute" but I have seen ones for sale that were about 6 to 7 inche size and at that size they can probably eat anything in the tank. I dont know how long it takes them to grow that big.

IMO------A 20g is too small to house an arrow crab. They can become very aggresive and will attack other shrimp as well as fish....HTH
