Thanks all! HEy Tangs_in_Pacifica, great too see some local folks here! OK, is it possible for a fish to kick the ick this fast? The tang is completely clear this morning, after having one whole side covered in the white spotty stuff yesterday. I had already been told about rolling the food pellets in garlic, and had been doing that for the past three days (since I got him). Also, I saw where you said treat the tank, well, this would damage the corals I have in there, correct? So if I don't treat the tank, every fish I add from now on is going to be at risk of getting Ick, right? And here's some info on my tank: 55 gal, plenum filter/skimmer/and Fluval 404, two powerheads in back corners for circulation, about 65 pounds of live rock, Live sand (about 5 inches) over plenum. As far as living things in the tank: Purple Tang, two clowns, a striped Goby, 3 turbo snails, two emerald crabs, one coral banded shrimp, hmmer coral, Starburts coral, Elegant coral, Flowerpot coral ad a cup coral. Plan on adding a bubble coral, cleaner wrasse and a reef clean-up crew in the next few days. thnaks all of you for you help, it is much appreciated buy a guy who would like to avoid his usual method of 'try it and see what happens!'
