Male Molly Fish With Cotton Mouth Disease?!

[Rollxr]

Hello everyone, there seems to be something alarming, my molly fish has like some werid white needle on his mouth but it doesn’t look fuzzy or white. Is this cotton mouth disease?!

Hi and welcome to the forum

Need more pictures showing the whole fish and make sure they are in focus. But going off the picture you posted, it looks like mucous. It doesn't look like a disease.

Hello Collin, sure here are more pictures but the white pimple, is that normal? Let me send you focused picture.

I would say it's excess mucous due to the fish having clamped fins and a bit of excess mucous on the edge of the fins.

Check the water quality for ammonia, nitrite, nitrate and pH.

Maybe do a big water change and gravel clean the substrate every day for a week and see if it helps.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank

Which edge of the fins you are talking about he has excess mucus?

Well the excess mucus on the edge of the fins, i saw a old picture of him 10 months ago and the edge of the fins do seem “mucus like” and i think that it is something he just had from his breed or somethinf. But to your thought, is his edge of the fin having excess mucus? A picture provided which was from 10 months ago.

Pectoral (side) fin in following picture has a bit of a creamy white patch on the edge near the top.

Also water parameters zero nitrite, .25 ammonia and less, 5 ppm nitrate. Ph:7.6

Do a big (75%) water change, gravel clean the substrate, and add some salt for a couple of weeks.

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.

When you first add salt, add the salt to a small bucket of tank water and dissolve the salt. Then slowly pour the salt water into the tank near the filter outlet. Add the salt over a couple of minutes.
