Go look at pictures of ich on the web and you will find plenty of things for comparison. A text-based description of a fish's description is rarely, if ever, sufficient to diagnose an illness.
Don't add ich meds to a tank with inverts. There are really only two outcomes: either the meds are invert safe and do not help the fish or the meds help the fish while killing the inverts. The problem is that chemicals that are certain to be effective against ich are also harmful to many other inverts, so meds that advertise effectiveness while being invert safe are almost certainly telling a fib somewhere in their claims. The only reason I say "almost" is because I can't discount the possibility that somebody will develop a miracle drug one day that is also invert safe, but, to my knowledge, no such thing exists in the trade right now.
