Hey guys, I was feeding my baby aka my fire eel and was super surprised to see a sore on his back. Does anyone know if this is a infection or something? Ive had hime for two plus years now and I’ve never see him anything like this. Water is in perfect conditions too. I did not see this on him yesterday. Thank you!

Not sure about the lump. I will say it's most likely a minor infection covered in excess mucous. The fish itself is also covered in excess mucous and that is an indication something is irritating the fish.
The substrate looks a bit sharp too and the fish might have scratched itself and now has a small infection where that happened.
-------------------
Wipe the inside of the glass with a clean fish sponge.
Clean the filter if it hasn't been done in the last 2 weeks. Wash filter media/ materials in a bucket of tank water and re-use the media. Tip the bucket of dirty water on the garden/ lawn.
Do a 75% water change and gravel clean the substrate every day for one week.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.
Increase aeration/ surface turbulence to maximise oxygen levels in the water.
Add some salt, (see below for direction on salt).
----------
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 (5 gallons) of water.
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, plants, shrimp, snails or any fish.
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.
When you do the daily 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.
