Thanks in advance for reading!

So I did a 50% WC on my 10 gallon today and accudently sucked up one of my cory fry. They are almost 3 months old, and this has never happened before which makes me wonder if he was sick (and weaker) beforehand (which allowed me to suck him into the siphon). I broke the suction as soon as I saw him in there, but I might have been too late...

Anyway so I just saw him stuck to the filter, so I unplugged it and he swam away. About 2 minutes after plugging the filter back in, I saw him stuck there again. So now he is sitting in a breeder net in the tank.

I did notice he appears to have a red head (like where his brain is) and a red tear maybe at the base of his fin (or perhaps just a pimple, hard to tell). Please see pics. He is still alive and will swim if you touch him (albeit with poor balance, like he spins as he shoots forward).

So... my questions:
1) Do any of his symptoms suggest he was sick prior to getting sucked into the siphon?
2) If so, what?
3) What is the best way to help him heal?

Water parameters recent readings? Species/common name?
EEEK sorry, I totally forgot to add those!!
Its a sterbaI corydora fry (hatched 3/1). Water parameters after the WC were 0/0/5ish (didn't measure before). No history of disease and no fish death in this tank except when the fry were less than 2 weeks old. However, I did recently add 3 female(I think) bettas without quarantine (yeah, yeah I know. But they seemed healthy and I didn't have any room elsewhere).

Just realized the 2nd attachment isn't showing (no idea why this keeps happening to me). Here it is again.

Honestly, not sure he'll make it, but clean water and stress coat would be my starting point.

Thanks! He isn't actually on his side, I was just trying to show the red spot. Got this while he was spinning/twirling.
I added stress coat to the tank and since I just did a WC the water seems pretty clean.
Thank you so much for your help here and on my other thread!!!

Shame shame no qt of new fish lol. Seriously though I’ve grabbed many a fish in the vac and they all turned out ok..right. If you don’t have a dedicated qt you could always poke some holes in that cup and attach it securely to the tank rI'm temporarily.

Lol yeah I just took in a bunch of fish from a friend so I'm a bit short on space ATM... that's also where the 3 bettas came from.
The cory is currently in a breeder net on the side of the tank. Probably better than a cup.
