Hi I just purchased 6 panda Corys and for the most part 5 of them seemed pretty healthy. But one of them I noticed has a thin curvy line in its tail and anal fin. I had no idea what it was so right now I put it quarantined in another tank but I was hoping someone knew what it might be? The picture is kind of hard to see my camera isn’t the best and I can’t upload my video that’s better

Yes sadly we found that out after trying to research into what was happening. We already bought some sand and it should be coming in a couple days :( although if you have any suggestions on any sand it would be welcomed. I want to make sure to make them comfortable/healthy as possible

It's excess mucous caused by something stressing the fish out.

Either take it back and swap it for another fish or add some salt.

--------------------
SALT
You can add rock salt (often sold as aquarium salt) or swimming pool salt to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres of water. If there is no improvement after 48 hours you can double that dose rate so there is 2 heaped tablespoons of salt per 20 litres.

Keep the salt level like this for at least 2 weeks but no longer than 4 weeks otherwise kidney damage can occur. Kidney damage is more likely to occur in fish from soft water (tetras, Corydoras, angelfish, Bettas & gouramis, loaches) that are exposed to high levels of salt for an extended period of time, and is not an issue with livebearers, rainbowfish or other salt tolerant species.

The salt will not affect the beneficial filter bacteria, fish, plants, shrimp or snails.

After you use salt and the fish have recovered, you do a 10% water change each day for a week using only fresh water that has been dechlorinated. Then do a 20% water change each day for a week. Then you can do bigger water changes after that. This dilutes the salt out of the tank slowly so it doesn't harm the fish.

If you do water changes while using salt, you need to treat the new water with salt before adding it to the tank. This will keep the salt level stable in the tank and minimise stress on the fish.

Aaahhh thank you so much for this!! The store is sold out currently so I will try my best with the salt!!
