In a few words, can you explain the symptoms? He has a small white thing stuck to his skin behind his eye

Was your fish physically ill or injured upon purchase? He didn't look it, but I had to treat for internal parasites about a month ago, used General Cure after finding him bloated with white feces. No new tank mates (his neighbor seems fine) so he might have already had them

Explain your emergency situation in detail.
Emergency might be pushing it, but I noticed this small white thing stuck to my black bodied betta's face when his lights came on this afternoon. It moves a little as he swims around, so I know it's not just a mark on his scales. It sort of looks like a dot with a weak tail, but I had to use my phone's camera to see it well enough to tell, my naked eye just registered a white thing that was moving a little. I don't think it's moving under it's own power, though. The only thing I can find online that comes close to what it looks like is anchor worms, but it's so small and I don't see the branched ends they're supposed to have.

I've gone back and forth between thinking it's nothing and shopping for all of the parasite meds. I put them through a round of meds a few weeks ago (see above), so I don't want to do it again unless it's really needed. I don't want to overreact over something so small, but if it's problem I'd like to nip it in the bud. His neighbor is bight white, so if he had the same issue it would be really hard to tell. I'm going to add pictures which will hopefully help with an ID. He's a difficult fish to photograph though, so quality of them is iffy. Is it a parasite? Is it maybe just his slime coat? If so, is that a sign of something else wrong?
