Cory Swimming Upsidedown On Bottom Of Tank

So he seemed to be acting oddly yesterday, being less active then usual. Today I come home to find him laying motionless of the bottom of the tank. Since removing him he seems to have perked up slightly. He's swimming around, as best he can. He's breathing heavily and still can't seem to right himself. None of the other fish in the tank show any signs of of illness. I can take additional pictures, I'm really looking to save this little guy. I'm also keeping in mind he may be quite old, seeing as he was already his full 2" length when I got him.

 

Information we need

-Tank size
-Tank temperature
-Ammonia, Nitrites, and Nitrates readings
-Is the tank cycled?

 

Tank is a 10G, temp is steady at 80F. It's been running since November 2016. Parameters are 0,0,50

 

Cories need a 20 G minimum. Therefore, a 10 gallon is too small.

Nitrates are a bit high. I would get them down to 20 or less

 

I'm aware with the stocking issue, him and his tank mates are getting a 55 soon enough. The nitrates aren't higher then the tank usually is(I know not good but stable is gotta be worth something). I'm also curious as to if starving could cause his symptoms? His tank mates are rather food hogs, and as he was added last to the group they don't give him much room to eat so I'm not sure if he's been getting what he needs. Is it possible that the nitrates affected him long term?

He isn't moving very much, but kinda spirals around when he does atm never seeming to be able to right himself...

 

From the pic, he doesn't look good I'm afraid. What other fish do you have in the 10g? If your nitrates are consistently that high, it's not very good for them especially since corys are sensitive to higher nitrates. I would be doing larger water changes to keep the nitrates below 20. Also, 80F is too warm for False Juliis. They prefer it below 75F. What are you feeding him?

 

Now I'm aware this is a bad idea. He's with afew small comets, hence the LARGE tank upgrade until the comets can get to their pond. The temp is on the down go as I just finished treating ick for the goldfish. Large water changes are done every couple of days to ensure everyone can survive until the big tanks comes in. And if nothing can be done for the poor fellow, I'm still interested in what might be causing this, as the other corys are doing perfectly fine. The corys are fed sinking shrimp pellets at he same time the goldfish are given an algae wafer, although I'm concerned the Goldie's might be eating those too...

 

Yeah, this is not the ideal setup for these fish. Goldfish are pigs and extremely messy. My guess is the water quality, dirty substrate and/or not enough food. How many corys do you have and are they all the same species? If you are able to set up the 55g, I'd move the comets in there and keep the corys in the 10 gallon until the comets can go to their pond. Then I'd move the corys into the 55 gallon as a 10 gallon is not suitable for corys long term.

 

They have proper schools, only ideal thing this tank has tbh. Come to think of it, I had a comet who acted the exact same way, which I attributed to ammonia poisoning afew months ago(he made a full recovery). Isolating this guy with even more frequent water changes, could this potentially help? Along with feeding him in an environment I can supervise?

And I just noticed; his vent? Fins seem to be fixed in place. When he moves his other find all move normally but these ones don't. Could that be the cause of the spiral swimming? Other then seeming slightly underweight and spiral swimming he no longer shows ANY signs of illness. He's always stayed still for periods of time so that is in character for him and his breathing has evened out.

 

I'm not sure about the fins but he does look very thin. I would start with daily water changes and give him some good food like frozen bloodworms. Not sure if he'll eat but worth a shot.

Hope you are able to move the goldfish to the 55 gallon soon.

 

Thanks for your help he's been moved and being fed more frequently as well as daily water changes and the goldfish tank is a work in progress as we speak

 

What species is it?.

 

He was sold to me as a Julii. Sadly he's passed on

 

I'm sorry for your loss.

 

Sorry to hear. Probably Trilineatus.

 

What's that DoubleDutch . If it's not starvation(which it looked like it could be), I'm all ears to other possible culprits

 

Trilineatus is the species name. As mentioned, it's water quality, not enough food and the wrong temp that are the likely culprits.

 

Trilineatus is the species of corydora.

 

Didn't notice the pic. Think it is a C102 Cory. Wildcaught, so maybe worms. I am not a 10G-fan. Nitrates 50 !!!
