Peppered Cory help needed!

[Sean13]

Hi so I got a peppered cory 3 days ago and I am new to this but he is a bottom feeder so i assumed he stayed at the bottom? He scaled the sides and shoots to the top of the water in corners and such. He just started this in the last day so Im wondering is this normal behaviour or is it an oxygen shortage?

If you've had one before and know their behaviour please let me know!

This is perfectly normal cory behavior. Cory's also have a posterior intestine that is modified to function as an air breathing organ. This means the fish often comes to the surface to swallow gulps of air and passes this to its rear intestine to supplement its oxygen intake via its gills

Make sure to Keep them in pairs or even better Trios! They need company or will become stress and diseased!
