So this morning everything was fine our clownfish was acting normal and eating fine. This afternoon I walk in and she is motionless on her side in the sand so I think she is dead but when I walk past she jumps up and starts wagging around. A couple hours later I walk in and find her in the same spot in the sand(next to the glass) and again when I walk by she hops up and starts wagging around. I come home from work a little later again same spot in the sand on her side. I fed the tank and she ate like a pig, as usual. She just keeps laying on the sand on her side. We have had her for almost a week now and no problems until this afternoon. Ammonia nitrites are 0 nitrates are only slight it's about 76 salinity is 1.023. All the other fish crabs and snails seem fine.
