Hey there, my fairly new gold severum seems to have a few specks of ich on it's fins. In my tank I have some scaleless fish, a clown knife and a black ghost knife so I was looking for treatment options for the tank. None of the other fish show any signs of ich, and i've checked every square cm. also in there is a lima shovelnose, farrowella (sp) cat, green terror, firemouth, and a bichir. I didn't think there were any exceptions for any of those guys but what do I know really. Can my knifes handle the salt needed? and can all of these guys handle 86 degrees?
