May be mucus cones which this fish is susceptible to and associated with skin irritation or mixed in with ich. Need a clearer pic and under white light intensity. You may have to resort to treating in a separate tank using coppersafe for at least 28-30 days. Often other tankmates will show no signs but do keep an eye on them moving forward.I was looking at one of my blue hippo tangs today and saw 2 white bumps along his top fin…is this ich? I’ve caught him pretty close to my anemone a couple times so could it be stings? Or maybe sores from rubbing and sleeping in the rocks?
