I have a 14gal tank with some LR
, 2 Clowns(well one now), 2 Camel Shrimp, Snails, crabs, some mushroom corals.
Everything has been going great with the tank, since yesterday some yellow polyps I had closed up and no longer are out and normal as usual. Tonight I noticed one of my clowns swimming on its side and darting around then he would fall down to the bottom, then pop back up to the top. Then eventually died. Any input of what could have caused this would be great. The other clown is doing fine so far. Is the problem possibly the nitrates? Ammonia? I did do a water change tonight and after my salinity level was just over the red. I took some out and added fresh water and I got it back down to 1.033. Just worried why the fish died and maybe it was just something wrong with him, nothing else seems to be affected.
