It looks a little skinny in those pics, but it's pretty hard to tell. What temp is it, does it have an air stone and how many of what kinds of corys do you have? I find mine eat as much as my bristlenose catfish and yoyo loaches, but until they got a school never moved much.

Yeah, sorry, edited it after, I started on this while there was a lot of noise and couldn't focus properly. I'm thinking by the parameters and such that it could be stressed or just wanting a bit more food. They usually take a lower temp than bettas and bristlenose, and in higher temps need more oxygen in the water. They also usually only school with their own colours and it's possible the bristlenose have been chasing them away from food. Sorry this response is late, I've just been trying to get my head back on straight. My corys are a successful mixed school but sometimes my bristlenose eat their food, and until I got the others they would barely move, just sitting there staring at the glass.
It's definately a little hot for the corys so it probably mostly wants an air stone.

I never could find out how many shrimp pellets to feed my Cory's so I drop in 2 per Cory twice a day....I have snails to eat the excess and all my fish are healthy and breeding (Corys that is) so I must be doing something right.
