I began treating my Electric Yellow Lab for Ich when I noticed he was rubbing himself on ornaments and the side of the aquarium, he never showed spots or anything and has always acted and looked extremely healthy. I have been treating him for over 11 days now with temp about 86 degrees and using the salt treatment. Today I notice he still rubs against surfaces occasionally but besides that appears perfectly healthy with a great appetite and everything, is it possible he does not have Ich and it's just a coincidence he is doing this? Or is there a high chance he has Ich?
