One of my corydora trilineatus is acting weird:
Is not shy at all anymore (does not rush away when i am near the glass),
swims up to the surface quite often (but not at warp speed).
Also stays vertical near the surface?
So turned on my airstone...

Looks very bulky too though.
So wonder if it is sick or pregnant?

Have 6 trilineatus and 6 adolfoi in there...

All others seem to do fine...

That is one very fat cory, too fat to be just eggs imo, what & how often do you feed?
I would starve them for a couple of days & see if her size decreases & I'd also do some extra water changes & keep a close eye on the stats.

Just did a test of my water:

PH: 6.5 (peet in my filter)
KH: 3 (low due to soil i am using)
GH: 7
NO2: 0.0 mg/l
NO3: 10 mg/l (max)
NH3: 0
NH4: 0

Only feed once a day.
Usually 1-2 pellets (but all my fish & shrimp eat from that).
Split them in 2 always.
My other trilineatus are way less heavy and my adolfoi even more less.

I have the same kind of cory and they never do that. Staying vertical near the surface does NOT seem normal. Cories sometimes dash up to the top to get a gulp of air very quickly, but they don't do this frequently and they don't do this slowly.

Healthy cories love playing near the airstone. Mine would spend several minutes a day swimming up and down the bubble stream.

I hope someone with more experience can come in and offer you some assistance. (Maybe try feeding him peas has a natural laxative? I haven't tried this before but lots of people here say it works.)

Good luck!

For what it's worth, I think these type of cories are tough as nails. I've only lost one so far, and my tank has been plagued by ich, overstocking, 88 degree temperatures (for the ich), 3 weeks medication with paraguard, and my general incompetence, etc. But these little guys are super troopers and seems to endure everything in stride. I'm sure whatever you're going through with a little luck he/she'll pull through!

Am cutting their feeding to every 2 days (and also feed less)..
So far the poor fella is no longer doing the vertical floating at the surface...so that is already a relief.
Hope i can manage his weight a bit so he's more healty.

The other trilineatus are less/not heavy
...so hope i do not starve them in the proces.
Also my adolfoi (they are already slender enough).
