I was feeding my fish and noticed this at base of rear dorsal fin. Thought it was ich and treated with aquarium salt and raised temperature until I could get some Ich X. But upon further inspection it doesn’t really look like pictures of ich. So I’m reluctant to treat with ich x if that’s not what it is. I’ve never had disease such as these before and want to do right treatment. They are all active and eating. PLEASE HELP.
