What is this red spot on cory? Is it blood?

[ShinobiFishKeeper]

I have been noticing these red spot on this Cory and smaller red spots on the other cories. There is no sharp objects and no aggressive fish only the cories and Siamese Algae Eaters unless the Siamese Algae Eaters are but I mostly see them just chasing eachother around and not cories. Awhile ago I saw this then it disappeared eventually now it's back. But they are always foraging and highly active. What is it?

He may have swam into the wood but I can't really see what it is, do you have a better picture?

It's right next to his fin

Unless the spots grow, or increase in number, or the fish behaviour changes, I don't think it's too worrying. It's not blood, that's for sure. Red on fish skin can indicate internal infection showing through, but typically you'd see than on the belly or the gills.

Ok. They are still eating and swimming around and I added some stress coat then it started to disappear. Its no longer big as it used to be.

Might have been a missing scale, now healing.. or some minor abrasion. But so long as they are eating, swimming well and behaving as expected, all's good.
