Yesterday I bought a small (~2") maxima at my lfs. It looked good, was fully opened in the store. I brought it home, acclimated it for about an hour, adding 1/4 cup tank water every 5-10 minutes. Nothing bothered it that I could see. This morning when I went to work, it was just a ball of slime. I just upgraded from 2x36 pc to a 70w mh + 1x36 pc and am still acclimating the tank to the increased light. Ammonia=0, nitrites=0, nitrates=10, ph varies throughout the day from 8.1 in the morning to 8.5 at night, calcium=375, alk=3. I have 2 ocelaris clowns, a skunk cleaner shrimp, 2 emerald crabs, some nassarius snails, a couple hitchiker hermit crabs (dwarf blue legs maybe?), haven't seen any pyramid snails, many small bristleworms (2-3") and spaghetti worms. Everything else in the tank looks good, even a hydnophora and lettuce nudibranch I bought at the same time still look good. I just want to know what happened so I don't make the same mistake again. Thanks for your help.
