i called my LFS today to see if they had gotten the mantis in, i am planning to buy, but no luck. the guy i was talking to knows me and suggested a pistol shrimp as an easier alternative, and possibly cheaper since they have been unable to get the smithii mantis i wanted. im not sure of the exact species, and anm actually on the phone with him this very second trying to figure that out... he doesnt know for sure... he thinks it comes from asia, and it is bright red, and forms a symbiotic relationship with watchman gobies. on the internet it says they pose no threat except to other shrimp... i guess my coral banded shrimp is screwed. how would an emerald crab fare? does the sand bed need to be a certain depth? i also read they like to hide in rocks, and dig in the sand. what would you guys call an exceptable price for this type of shrimp? the store said they will probably be selling them for $20-25. also if there is anyone with first hand experience, advice would be appreciated.
