So I noticed today that my cherry shrimp is laying on its side, some of its legs still moving, but it can't seem to stay upright. I think I may have accidentally nudged the driftwood in the tank, and it was underneath and mistakenly injured. I put a nugget of crab bite next to it so it could eat, but its forcep-like feet in the front are hardly moving, just the back "swimmerettes." I don't know if the legs were damaged or if it's just sick. Anyone have a clue? I wonder if the new water changed the temperature enough to cause shock?
