He might be gasping for air. Do you use CO2 in your tank? The oxygen level goes down in the tank if you are using CO2 in your tank with plants. Plants breath CO2 during the day and oxygen at night.

Tell us a little about your tank. This will help us help you Size, water parameters, tank occupants, co2? Are all the occupants at the surface frequently or just the one cory.

maybe he's afraid of the dark  ;D just kidding! I really don't know all of mine make runs to the surface but they don't stay there. I have 8 in a 29 Gal. 2 pandas, 2 albino aeneus and  4 green aeneus corys. Is anythig floating on the surface he might be trying to catch? When corys go to the surface for air on the way down they usually expel a tiny bubble of air. Does he do that?

Corys have the ability to go to the surface and take a breath of air, then it travels through the intestinal track where some of it is absorbed and the rest travels on out the anus. Thus the little bubble you see expelled. Maybe for some reason the bottom layer of water doesn't have enough oxygen for him at night. Try stirring the water really good(bottom to top) with your hand before you turn the lights out tonight. Worth a shot and just a thought.

I just got some emerald cories and they don't wake me up because they seem to stay at the bottom. But when they were in the bag on the way they went to the top and and as they went back down they made a bubble. But the problem is the small one I think is a male and the other 2 are females but the male is smaller and the females chase him around is this normal?

Yeah their just playing, I have 10 of various kinds in a 29 G and they constantly chase from one end of the tank to the other.

Must be pretty loud, amazing for such a little fish. How close is the tank to your bed?

But the bad thing about the females chasing the male is that the females chase him away from the food and they are big and fat and he is small and skinny. Will this stop before he dies of starvation? And he seems to hide a lot but the other females come out and scavenge for food. I really worried about this male with him being so skinny.

Males are naturally much slimer than the females. corys tend to scavenge all the time, but if you think he's hungry try dropping food at opposite ends of the tank.

His gills were red. he never moved, he didn't eat, he was breathing rapidley. So I return him and from what he said it sound like they weren't going to try and treat him they were just going to flush him.
