Is This Normal Behaviour

[TraceyB]

I was wondering if it was normal for corydoras to swim to the top of the tank for air

Water test results show

Ammonia 0ppm
Nitrite 0ppm
Nitrate 5ppm
PH 7.2


Still treating for Ick using protozin and temp is raised to 27c have air pump going with full length air curtain the length of the tank (86cm)

yes, they dart up for air, stupid ain't they.
