My female cory catfish is doing it again

[16gallontanker]

The biggest albino cory I have is gasping for air again and the hob filter is still on and so is the sponge filter. Is this ok? Here are my water parameters

How hot is the tank? If it's warm, even with a HOB and sponge, it may not be enough oxygen


That said, many cories do like to search the surface of the water like that. Mine do it a lot in the floating plants. I've got an old video somewhere of my old aenea doing it and you could hear them doing it every single night.

Just looking for food. Ironically mine were also albino aenea

Video of the fish and surface turbulence created by the filters?
Upload video to YouTube, then copy & paste the link here.
If you use a mobile phone to film the fish, hold the phone in landscape mode so the footage fills the entire screen.

Have you done anything to the tank in the last 24 hours?
