My cleaner shrimp just died. Trying to figure out why it did. Ive only had it for 3 days. Acclimated it through drip acclimation for 2 hours when i got it. I then let it in the tank. It was very active sunday and yesterday but today it kind of just stood in the same spot most of the day. I just recently found it on its back dead. I removed it from the tank and took a look at it. Looked normal. No clue why it died. Ammonia 0 Nitrites 0 Nitrates 10 Salt 1.023. Any ideas?
