Oddly enough, they are all doing fine. we have 5 red leg crabs, 2 emerald crabs, 2 small snails, 1 giant turbo snail and an anemone that are doing fine. we lost our cleaner shrimp for some unknown reason about 2 weeks ago and he's not been replaced. I did move the anemone yesterday to the big tank for fear of it dying, so it's not longer in this one, but until then he was doing just fine.
I plan on using a water clarifier chemical today since there's been no progress at all. Even water changes only temporarily and partially clear the water. I'm also going to take a water sample into my LFS, maybe they can give me a clue.
