He might be bloated or have SBD (Swim Bladder Disorder) the good news is that this isn’t contagious! For bloat, I heard somebody on the forum say you can mix one tablespoon of Epson salt with one gallon of water and soak them in there for ten minutes. If it’s SBD, this is caused by over feeding, then you would not feed it for three days and then feed them blanched peas. Do you have a heater? cold water slows down there digestion so that could also be a reason if you don’t have a heater.
Hope your Corry gets better!

Cute little guy. Is it still swimming sideways in the quarantine tub? I know one of my corydoras likes to sleep against plants and rocks so he's turned sideways. Gets me every time.

Could also be that your cory dosen't like living with just one other cory

One quick note is that salt is bad for corydoras, so I would refrain from using it... which is one of the reasons that curing cories of things can be tricky.

De-ionized salt isn't bad for corys. Their just sensitive. So you want to make sure to get the time and dose right and monitor them extra carefully. Unless their together then they're not happy.

Im gonna feed the cory a pea after ive finished work hopefully it hasnt died by then! It moves about then stops goes upside down then swims again

Hi sorry to say but a pea won’t do anything, that looks like a growth/tumour & by the sounds of it I doubt anything would help at this stage. Sadly I think I’d have to suggest euthanisia.

I agree for the fullest

Yeah i got home and it had died R.I.P cory

Sorry to hear.
I've been thinking about this thread and the course it followed.
It is one of the many threads OP shows a real issue with a good clear pic.
Then the OP is asked to fill the emergency template, does so and then gets several advises for treatment for issues I don't see in the pic or read in the emergency template.

I don't want to be rude and I am definitely ain't a know-it-all but please please don't advise any treatment if you're not sure.
Several treatments are quite harsh for fish and if not needed, do more harm than good.

I don't tell anyone isn't allowed to provide advises but please be careful.

Also in a lot of cases I think the question to fill in an emergency template is useless and overdone. But that's my personal opinion in cases with clear pics.
