Is this gill curl or damaged gill?

One side of my gar's gill looks like this. Is that gill curl or damaged gill? It might've damaged itself since the tank at my LFS was pretty small and was pretty crammed.

Okay, I'll post some clearer ones later today. If it is damaged gills, will they heal?

I can't seem to get clearer pictures, but I think they are at least closer.

In these images it looks like gill curl, I would increase the flow in the tank and do lots of water changes
