Quick Question

[Nevergone815]

well i have recently bought a full grown emerald cory (i felt bad as it was stuck in a tank by itself and when it did get a tankmate it was a big fat pearlscale something (looked like a goldfish kinda) that just bounced around the tank crushing the poor cory. well he randomly drifts upwards or even right from the bottom, darts straight up and breaks the water. i am pretty sure that this is normal but i want to know what exactly is the reason for him doing this.
thanks for your help

hmm, not sure if this is right cos i am new but i have corys. Someone told me that they have the organs that breathe air as well as gills so they shoot up to the top to collect it ever now and again.

My corys do this also.

phew. i thought it wasn't anything bad just making sure and getting the reason for it thanks for the info. until i hear otherwise i will assume that that is the reason he is doing it

Corys do also breath via the surface... however they should only do this occasionally... if they are doing it continually, check your water stats...

Mine do it too sometimes. Not very often. The younger ones seem to do it more then the older ones do.
Slightly o/t but love the puffer in you av bogwood. Looks likes one of my puffers to a T.

Hi Nevergone815

Corys are able to swallow small amounts of surface air and absorb the oxygen through their intestines. In their natural habitats this helps get them through times when the water gets muddy. Even though their tank water might be fine, they sometimes do it once in a while.
