Actually, the cleaner shrimp has "disappeared" for the last 2 weeks. The Tang was bothering the tang, i.e. just following it around everywhere. So the shrimp hid in a deep cave that's built into a decoration thing. And has never come out. The shrimp has been in the tank for about 3 months. Never had an issue, just the tang. All other fish is fine. I have a Tomato Clownfish, who during the first few weeks appeared to have developed ich. But wasn't really spots as much as it was a pale white spot underneath it. It has been long gone. The Yellow Tang has actually never been so BRIGHT. He always has his top and bottom fins fully extended and seems to love being in the tang. Never aggresive towards others really. And I don't know if this is normal. but I think the top part of his body is turning SLIGHTLY orangish in color. And I hope this isn't bad, but he has a slight line on either side of his body that starts from behind his eyes and curves all the way back to his white diamond thing on his tail. There aren't any noticeable lines, except some that look a bit like his bones. Also around his stomach area, it's a little green. Just a little. I guess he's been eating alot of sea weed.
astride13. I'd check the filter, because my tang really tugs on the seaweed as he eats, which breaks the big piece into smaller pieces and they get fed to the filter, powerhead, or protein skimmer. He seems to like flakes and brine shrimp alot more than seaweed. However i leave the Sea Veggies in there just in case he gets hungry.
