Hi,
I might be a bit of a "naturalist", but I have found the best treatment for ick is just to leave it alone, no chemicals. I simply raise the temperature to about 27C, about 84F I think, and leave them alone. I have an ozonizer on my tank which seems to work well in preventing re-infection. I also feed garlic, I crunch mine in a garlic crusher, then put it into a small glass of water with b/shrimp and nori, and then leave it to soak for a few hours. It definitely did no harm, but I'm not sure how much was acheived. My fish are all ick-free at the moment, the best seems to be just to ride it out. After a while, all your fish will be over it. However, ALL IS NOT WELL YET! Do not introduce any fish for a while, at least a month, and more like 3 months for more sensitive fish. Even though there will be no sign of ick, a new fish will be immidiately infected. Anyway, what I'm saying is that I've always had the best luck with no medication, slightly higher temperatures, an plenty of Spirulina flakes! I might have to try your garlic concoction, as I am keen to experiment further with this.
Fishgirl: where are you going exactly? I've seen the reefs of the islands of Hawaii and Kauii. Hawaii didn't have as much variety, but then again I didn't see that much. I saw a lot more of Kauii, there were some Humuhumnukunukuapuaa, but there were heaps more of the reef triggerfish, (R. aculeatus). The other thing to look for are some beautiful Naso tang (N. lituratus) They are jet black with all the same markings as a normal Naso tang, an absolutely stunning fish. It was about 10 years ago I was there and those things still stick out in my mind.
If you ever get the chance, come over to Australia. We have so many fish, the variety is amazing. It seems that the further west in the Pacific you go, the greater the numbers and diversity of life. I'm sure you'll have a great time, though. Also, do marine biology when you leave school, you won't regret it if you're really interested. There is a lot of great research opportunities. In Australia, we have a University right on the Barrier Reef, so plenty of field work there!
Regards,
Tom
