I'm surprised that no one said this yet but gasping is a sure sign of ammonia poisoning. And if you're using test strips I bet that if you got a low ammonia reading it is false.
How do you two know this tank hasn't cycled by itself already? I've seen many unmanaged fishin cycle take a month. Yes what they are saying is something I would look into. But in previous post I don't believe anyone asked if the tank was cycled or anything. He probably had the few fish to cycle the tank like the store said and now a month and half later can get more fish like the store says. Possible for it to have cycled on its own. And in which case water changes would not help the issue. Well it would until all the oxygen you added during that time is used up. If the tank is cycled with good parameters what would the answer be? An air stone or surface agitation.
Gasping at the surface, oxygen deficiency. Number 1, why because it's the easiest fix. Good surface agitation. Sorted.
Ammonia is all manor of issues, mostly related to the skin cells and gills. Not always at the surface, if they try to escape maybe yes, listless behaviour at the surface though? That points to O2.
If it's mainly first thing in the morning run an air stone when the lights go off until they come on again.
(When plants are not photosynthesising they are respirating) that is, consuming part of the systems oxygen budget.
They don't drown as such, they asphyxiate. (Like being strangled) oxygen starvation. Some species like Corydoras drown if they can't get to the surface.
See oxygen deficit in a water course.
He'll be back, it's his thread.
Even a cycled tank should have weekly water changes.
I personally know the tank wasn't cycled because of other threads started by stardaddy.

Don't all Cories need sand? But interesting I never knew the couldn't take in enough oxygen through their gills. I guess that makes sense why I see them go to the surface every once in awhile. one of my sterbai Cories will blow a line of bubbles across the surface every once in a blue moon. Must have something to do with that.
So if my Cories come up a lot it shows there is lots of oxygen in my water?Could be gas
(the regularity of the surfacing is a good indicator of 02 in the water)
