Cories Odd Behavour ?

[smithyif]

hi all i was just wondering why my cories have started to shoot to the top of the tank then dart back down again ? i havent noticed them do this before and just wondered if there was a reason

perfectly normal. they take air from the surface.

Mine do that a lot, not a problem.

My trilineatus cories do this as well.

Got 6 peppered corys; they dart up to the surface all the time.

Mine used to do this but very rarely do now, is that weird? Should they do it more often?

My Panda cory's used to dart up to the top when they were in my 120litre tank, when i upgraded to a 200litre and rehomed them in it they stopped!!!!
