Hi, I'm hoping someone can help me identify what might be going on with one of my endlers. I brought home two females and a male for my 10g planted tank yesterday. The tank has been up and running for over 6 months and the only other livestock in the tank are some neocaridina, two nerite snails, and a bunch of ramshorn snails.
Parameters:
PH: ~7.5
GH: ~10
Ammonia: 0
Nitrite: 0
Nitrate: <20
Temperature: unheated, but has been between 71 and 73 F since I put them in yesterday
All 3 endlers looked perfectly healthy and happy yesterday. This morning, I can see what looks like a spot/injury on one of the female's mouth, right side of body, and it seems as though the right-side fin is damaged too. The other female and the male still look totally fine.

I have Ich-X on hand, but this doesn't seem like ich to me? But these are the first fish I've kept in a long time so I could be wrong. Any help would be appreciated. Thanks.
edit: after watching them for a while it seems like the male (which is about half the size of the female in question) might be bothering her. Is it possible these are actually injuries from the male? And if so, why would a male harass one female like that?
