i recently to a pair of pink bar gobies and pistol shrimp off of divers den and they came in looking great and I've had them of a couple days now and all they do is sit in the back of the tank or in the back right corner and they haven't tried to make a borrow or anything they just sit back there, they both eat great but they don't really move. my question is if that is normal or not I've never had a shrimp goby before and I've read that they are supposed to borrow and mine haven't yet. they are in a 34 gallon solana reef with a deep sand bed and they are they only fish I've checked that parameters they are great all the corals are thriving but i just don't know if theres something wrong with the fish or not, any help is greatly appreciated and thanks in advance!
