powder blue with ick

[boozerell]

Last night my powder blue tang looked fine, nothing wrong. Has been eating really well and still is. This morning spots all over him...ick. Now, I can see marks, but the white spots are off...I'm assuming the cleaner shrimp is picking these off. I've added garlic and selcon to his food. I'd rather not remove him from the display tank, and stress him anymore. Any suggestions?

stress usually brings on ich, could be a new addition or water a little off, also a neon goby does a fine job, better than shrimp, be patient and let nature do it's thing and your powder blue will build up a nice immunity over time and eventually hardly ever get ich, also remember they always do much better in larger systems, your 90 is on the small side.
