Sick Cory!

[Cattilara]

Hi,

There is a small panda cory in my mothers tank that is not eating. It isn't shuffling around the bottom like the others and it goes to the surface for air a lot.
It doesn't look skinny or bloated yet, no colour changes in body or fins. He just sits there with his whiskers back looking sad.

The tank is 120L pH7, no ammonia or nitrite and has regular water changes with tank water.
It's a peaceful community tank with several types of corys, guppies and a few white clouds.

Is there something we can do?

What test kit are you using.
How may fish of which type.

What do you feed the fish.
Do the whiskers look short and thin.
Does he act listless and lethagic.
Does he lean to oneside when resting.
What do his gills look like.
