Gasping for air
All right another one of my cory's was acting very strange when I got home, he sat at the bottom of the tank, looked like he was resting, but I've never seen this behavior before. So I did a water change, probably 30%.
Few hours later I am noticing the same cory swimming up to the top of the tank upside down and breathing air, now I read that this is normal behavior for them, to get air like other fish, like Platys for instance, but I've never seen him do this before should I be worried?
I dont know my tanks peremeters, sorry, all I can tell you is that its a 28 gallon, housing neons, other tetra's, cories, and platies. Everyone else is doing fine. Oh and the temp is at 80 degrees,
