Ok folks, really really need your help. We purchased a Squirrel fish at the LFS the other night. We love the little guy, but he has saltwater ich spots on his tail and pectoral fins. I lost everyone of my fish about 6 weeks ago due to ich. Have since treated the tank with Ich Attach, did a water change and let it sit fish-less for 4 weeks. I added a blue damsel 2 weeks ago as a test, and he/she is doing fine. Added the squirrel fish on Thursday night and already has Ich. It's early, so looking for advice, this Ich problem is killing me (and my fish). Tank temperature is 81. Water specs as of last night are: KH: 13.4 (240ppm converted in German degrees) PH: 8.3 No2: 0 No3: 0 Ph: 0 (BUT, I have lots of hair algae, so guessing if that wasn't there it would be much higher) I have a RO/DI unit ordered and on the way. Once received, will slowly start doing water changes to replace the tap I used. Back to the squirrel, should I just keep an eye on him and hope it goes away? Fresh water dip him? Medicate the tank (I REALLY hate to do this)? Other suggestions? Thanks!
