Okay so I was advised to vaccuum my gravel and do big water changes every day for 2 weeks and i have been doing this and my fish is getting worse. Now he has a white patch on his back. I dont think water changes are fixing this not to mention the original problem(white fins) has only got worse. I thought it looked like columnaries or whatever but I was told a protozoan. I know nothing about fish and the disease symptoms sound the same I'm so confused on how to help this fish.
 
It's excess mucous and I would say it's an external protozoan infection (Costia, Chilodonella or Trichodina) because the water changes didn't help.

You can try salt, Malachite Green or Copper to kill external protozoans.

You can add rock salt (often sold as aquarium salt), sea salt or swimming pool salt to the aquarium at the dose rate of 2 heaped tablespoon per 20 litres of water.

If you only have livebearers (guppies, platies, swordtails, mollies), goldfish or rainbowfish in the tank you can double that dose rate, so you would add 4 heaped tablespoons 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, 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 but the higher dose rate will affect some plants. The lower dose rate will not affect plants.

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.

-------------------------
If there's no improvement after 3 or 4 days of salt, then look for a medication that contains Malachite Green or Copper.

Malachite Green is carcinogenic (causes cancer) so avoid getting it on your skin and wash hands and arms with warm soapy water after working in the tank.

Copper will kill shrimp and snails.

-------------------------
Make sure any medication you get is safe for scaleless fishes (loaches, catfish, eels). If you can't find a medication suitable for scaleless fish, use a normal medication at half strength.
This applies to chemicals and not salt. Follow the directions above for salt.
 
Thank you so much colin. So the salt dosing you said is fine for my yoyo loach? I thought they couldnt tolerate salt?

The dose rates are fine for all fish including loaches.
