Corydoras keep going upside down?

[mgillett88]

Any ideas on what’s going on here? The one has been on the side of the glass, the other keeps going upside down. There both alive and keep swimming down and moving round the tank.

Are they moving fast and kinda jigging a bit?

When I disturb them yeah. Just our of character. Had a couple of issues in the tank with other fish but been watching these intently as there entertaining.



This one has moved around a bit. Her/his mouth is moving. Going to do a partial water change as I’m a little concerned.

Have you tested the water parameters?

Yes. Ammonia slightly high. Has been for a couple of days now. Been doing partial water changes daily.

I would definitely find the problem causing the buildup of ammonia, and do a large water change immediately.

Cories are very sensitive to nitrites or ammonia, and being fish that live near and on the bottom it makes it very easy for them to be exposed and become ill quite quickly.

Water change has just been done. Added Tetra stuff to make the Tao water safe and some stress coat. I’ll observe for the next few hours. Let the tank settle. Then test again. If it’s still slightly high I shall do another water change.

Well if they are both glass surfing they Id say they are getting ready to breed. But since it looks like one of them if (floating?) upside down, that looks worrisome. Like others mentioned, do a large WC and add prime to protect them from the ammonia.

Thank you for your reply. I did find it odd that it’s only 2 out of the 5 behaving this way. I did think breeding initially, as I know they lay eggs on the glass. They’ve settled down now since the water CX.
The one swam up kinda rolled over for a moment then righted himself and swam back down and carried on munching. I noticed after fed the fish bloodworm last night when it sank to the bottom a couple of the Pandas kept going back to it. Maybe bloated?

Hello, pandas are on sensitive side of corydora family. Ammonia should be kept at about 0.25-0.50 till tank cycled. Higher ammonia than this will damage fish & kill. They also require a lower water temp(68-77°). Hope this helps you!

HI there. We’ve actually just lost one so any information would be really helpful right now to prevent any further casualties.
At 24 degrees C water temp at mo, do you know your Fahrenheit conversion? Lol

Thank you for assistance.

Just thinking that was in high range & to thrive they needed to be in middle. Sorry for confusion.

No problem mate. Done some research and managed to lowered temperature to 22 which suits all species on tank.

Looks like ammonia was the culprit with your pandas as in your last pic it looked like his gill area was quite red. I'de continue testing water daily and do WC's as needed ( from what i've been reading and seeing on here pandas have been having a very bad run lately) Good luck!!
