White stuff growing on Dwarrf Gourami NEED HELP!

Their is White stuff growing on my gourami's fin and im sont sure what it is if anyone could help that would be great

Looks like fungus. You can use a fungus medication or try daily 75% water changes along with 1 tablespoon of aquarium salt per 5 gallons of water. Dissolve the salt in a little tank water first so it doesn’t burn the fish. After first dosage, only add 3/4 tablespoon of aquarium salt after daily 75% water change. Do this for a week and see if it improves. Gourami’s can handle salt for short periods during treatment. If not improved in a week, you’ll want to get a fungus medication. Fungus grows faster in warm water so you may want to turn your heat down a little too. @Colin_T is this correct regarding salt and gourami’s? Any other suggestions?

Hes also looking bloated

It's just a bit of fungus and salt should do the job.

You can add rock salt (often sold as aquarium salt), sea salt or swimming pool salt to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres (5 gallons) 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.

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 2 heaped tablespoons per 20 litres and if there is no improvement after 48 hours, then increase it so there is a total of 4 heaped tablespoons of salt per 20 litres.

Keep the salt level like this for at least 1 week 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 (4 heaped tablespoons per 20 litres) will affect some plants and some snails. The lower dose rate will not affect 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.
