Well EJ it looks like your
salinity might be a little low. How are you testing it? Do you have a refractometer? If not I would invest in one.. If you want a stable tank you have to start with the water. I got the Ruby Reef in the mail but never used it. Thank God! My poor wrasse mysteriously disappeared. He didn't carpet dive or anything. I think he might have just been a sickly fish to begin with and finally succumbed to whatever was ailing him...Maybe cyanide? Who knows. I suspect my Brittle Star ate him though cause he is now hanging out where the wrasse used to sleep...EJ I wish I had some good advice for you. I do know that the Hippo tang you have are notoriuos for getting ich. I think raising your temp and adding some garlic to the food may help but who knows they may not work...At this point I guess it's worth giving it a shot. Good luck.
