Fish Crazy
They like groups alright, the more the merrier, providing the space is sufficient.
However, I noticed a couple of things in the video, which you may want to consider. One of them potentially has to do with the apparently odd behavior of the single cory. The other has more to do with overall long-term cory happiness and health. I will start with the latter.
The gravel yo have should better be replaced with sand. What you have, allthough relatively fine as gravels go, is too coarse and can be damaging to your cories in the long term, specifically affecting their foraging, damaging their whiskers and affecting overall behavior.
But one issue you may want to check is that it appears that the individual cory showing the odd behavior, is missing an eye, its left eye. If so, that could explain in part the odd behavior. Take a good look; I may be wrong, but that is something I think I saw, perhaps best in the images below (
first, the left side, possible damaged or missing eye; second, the right side having an eye, but potentially showing some cloudiness?). I know sometimes pictures lie (show "oddities" not corresponding to reality, but it is worth a good peek).
