Tomini Tang patches

[Matty Ice]

My Tomini Tang has these patches. Anything I should be worried about? I’ve had him for about 6 months with no previous issues. 65gal tank. Seems like they appeared a week or two after adding a few sps frags and Algae Barn Copepods.

Temp: 78°F Apex/Hanna
Ph: 8.2

Eats well. A mixture of sea weed sheets, sea weed extreme pellets, frozen mysis, TDO pellets, frozen fish frenzy. Frozen foods are soaked in Selcon.

Tank mates: 2 clowns, six line wrasse, gold head sleep Goby. A mixture of inverts.

Take some white light photos and a short video if you can. Any recent additions?

No recent additions other than the frags and pods

the video better than pics but still hard to see. I believe if you see them come and go, may be stress marks but can also be a bacterial issue - Need to see body clearer.
If bacterial, you can start with ruby Rally Pro which will keep this in check and prevent further spread. If it becomes pronounced, treatment in a separate tank using Seachem kanaplex

Tang let the cleaner shrimp scrub him down a few times I saw this week. I have a school of Chromis in my qt at the moment. Is the rally pro a dip or a quarantine process? All my fish have been through quarantine but never did any corals or inverts.

When fish posture in front of cleaner animals, there is very often a reason, that is the fish feels an "itch", and that can be from flukes on their skin. Watch the tang for flashing/scratching, if you see that as well, I would consider treating the tank with Prazipro, 2x, 8 days apart.
