Angelfish with brown mark under lip after I come back from vacation

[Toast]

Tank: 40 gallon with very small snowflake eel, 1 skunk shrimp, 1 peppermint shrimp, 1 urchin, 1 royal gramma, 1 yellow angelfish, handful of hermits and 2 conches, some snails

Hi, I introduced my yellow angelfish to my 40 gallon I wanna say a week or two ago. Since I first introduced her I've noticed she has some odd behaviors, like rubbing her side on my snowflake eels snout? She swims perpendicular to him and touches him, it's really odd but he just lets it happen and does not try to bite her at all, he's very small and friendly. He lets my skunk shrimp clean him and lets me pet him so he is not a concern in this post.
She was bothering my peppermint shrimp on the first day she was introduced, so I bought a skunk cleaner shrimp for her immediately.
I left on vacation on Saturday morning , having gone to celebrate my anniversary with my husband in the mountains. My tanks were all taken care of before I left and she did not have the brown spot. I came back 5pm Monday.


In the meantime, my FIL was looking after all of our tanks, and subsequently the salinity spiked in the 40 gallon to 1.034 from the hot weather and no top offs. My angelfish developed a weird brown spot under her lip and I've been observing her over the past few days. It doesn't seem to be getting worse but she has been visiting the skunk a lot and seems very bothered by it.
She's still eating and swimming like normal.

Is this a salinity sore? Is it uronema marinum?
I'm worried for her.

Sorry for low quality it's really hard to take a photo of her lip.

Looks like a nick or injury which should heal on its own. Keep an eye on it for reddening or swelling. If so, treat in separate tank with seachem neoplex

Welcome to Reef2Reef!

I can't really see the discoloration you are describing - it is under the upper or lower lip?

The salinity spike was pretty high, was the FIL topping up with seawater? A tank would have to evaporate pretty far down to reach 1.034 on its own....like 30 to 40%.

In the second video, the angel is desperately trying to be cleaned by the shrimp. Fish do that when they have some parasite issue. It could be related to the brown spot, or it could be flukes.

The angel is a bit thin, be sure to feed it multiple times a day.

I don't seen any issue with the fish (i.e. what you're concerned about). If the fish is eating, swimming normally, I would tend to watch it. Except as noted by @Jay Hemdal
