Ive already posted this topic before, but i only got one answer. I have 2 "algae eating shrimp" what i think are amano, and all they ever do is hide under a rock. I can see them under the rock, but i have never seen them out before. Ive had them about 3 weeks. I think they molted right when i got them. I got them to get rid of some hair algae, but haven't noticed anything. pH 7.0 Nitrite 0 Nitrate (not sure but ive had it tested and it is good) ammonia 0. Im not sure about hardness. The temp is about 25 C, i think like 76 F. Please respond. Thanks.
