I purchased some LR from Florida last week, on the bottom of the bag of rock was a mantis shrimp, I have moved it to it's own 1 gal nano cube. the problem is I don't think it is eating, I've try frozen brian shrimp, flake food, a piece of shrimp meat, minor from bait shop, finely threw one of my margarita snails in the tank two days ago, that is still alive. the tank is clean , i've changed the water. Any suggestion on what to feed this thing?? I guess I should stop worrying about it and let nature take it's course.
