Strange white circle on sailfin tang

pauljcooke · 04/09/2019, 03:17 AM

Hi, does anyone know what this could be? Marking just appeared over 24 hours on side of body. Not a raised mark or ich like mark, almost embedded in his pattern.

Sting from a coral or anemone?

No anemone but possibly the long tentacle fungia or torch...

Looks like he got bit. Is the tang a new addition?

Possibly a ciranolid isopod.

I'm gonna guess it's a scrape from sleep habits.
I've had tangs that end up with all types of scratches and cuts if they sleep in crevices in the rock in my tank. I figure they wedge themselves in and get scared when something (snail, crab or whatever) touches them inside the hidey hole which causes a bit of a panic.
Have a yellow now whose dorsal fin is missing a good size chunk every few weeks. It's an open water sleeper but he startles easy.
If they're healthy they heal on their own. Just keep an eye on him and make sure he keeps eating.

Thanks all. He seems to have healed already, but now has some suspect spots which look different but I'm keeping an eye on him...ich is really one of the most annoying things there is. I quarantine but it always finds a way... This tang has not had a happy first two weeks in the tank!

Beautiful tank!

My tang occasionally has something like that. All of my fish were rigorously quarantined, so I just assume it bumped into one of my many long-spined urchins. It's always gone the next day.
