Clownfish skin lesion

[RobertK]

I just noticed this whitish spot on the side of my clownfish today. Also just noticed there is a little black thing by his mouth. Are either of these anything to be concerned about? This fish is captive bred (as are all its tankmates), I've had it a couple years but all fish were just transferred to a new tank a few months ago with new diver collected gulf live rock and live sand. The other 8 fish in the tank all look fine, including its clownfish partner. Thank you!

This looks to be a physical injury or bite. Keep an eye on area for signs of healing and Not turning red or sore which would suggest infection and treatable using Seachem Neoplex in a separate treatment tank

The mark on the chin looks like a stray bit of melanin, normal to see.

The larger white mark looks like an injury. Gulf live rock often carries with it a micro-predator isopod. These live in the rocks and swim out and bite the fish. They aren’t true parasites, and usually die out in a few months. Some people have nused baited traps to get them out.

Look up cirolonid parasite here…..
