I recently added a coral beatuy angel w/o quarintining him. Just my luck he did have ich (and ended up dying) as now does my blue hippo. I gave the hippo a freshwater dip and he perked up today and is looking better. I have one clown fish, lawnmover blenny, yellow citron clown goby, and the hippo. My first question is are my other fish likely candidates for ich even though they don't show signs already? And secondly is how do I go about treating this in my reef tank. I heard from the lfs to just keep dipping the tang as needed and otherwise just waiting the disease out. Is this accurate info and if so how will I know when the Ich' s all gone? Thanks!
