Tang External Parasite ID and Treatment

[MarsReefer]

Woke up this morning to a nasty spot on my tang. He's been in the tank 2 months, all livestock in my tank have been QT'd through Dr. Reef. Nothing has been added in the tank since the tang. When I added the tang he was also added with an Anthias and some cardinal fish.

Can someone help me ID what this might be and what treatment would be? Due to extensive rock work any treatment will likely need to be in tank. Tank is all LPS corals with fish and inverts.

Thanks in advance

Though you could try Ruby Rally Pro, there really isn't a great 'in tank' treatment. I can't tell - is it a flat 'injury' - or is something physically attached to the fish? If indeed it is a parasite, prazipro can be used in the display.

If you send pictures or video to Seachem Support they would be the ones to ask they are very helpful

The small extension you see is flapping around like a worm, so I assume its something attached. He doesn't stay still long so its hard to tell for sure

Injury with a skin tag. Seachem neoplex best IF it becomes infected otherwise keep an eye on it for now

Are you sure it’s a worm and not a skin tag from an injury?

The only parasite that looks like this is the very rare species of female copepod whose egg cases can extend through the skin out into the water. I’ve never seen those on a tang - mostly on firefish, puffers and some gamefish species.

Yeah I took a closer look and it could be a skin tag. I’m going to keep an eye on him for a few days before doing anything. Hopefully it heals over without issue.
