White graze

[LTurner97]

I cleaned my tank yesterday and in the evening noticed my Cory had a red blotch on its side , I googled it and it suggested I do a salt water bath for 15mins and return the Cory back to the tank , this morning I noticed the red blotch had disappeared however still one very unhappy fish sitting at the bottom with clamped fins, later on today I can see there’s like a graze in the same area with what looks like white also , any advice please

That looks like just an excess mucus which is the fish's way of covering an irritation and/or protecting it from infection. The issue is not knowing what the cause was of the red spot. Was it an infection? An injury? An external showing of an internal problem? Without those answers, the best way forward is to do nothing and let the fish recover if it can. Salt is very hard on Catfish so it's not that unusual for a catfish to be stressed after a salt bath.
Personally, I would have placed the fish in a separate quarantine tank to recover because whatever it was that happened, happened in the main tank. After the fish recovered, then it could go back into the main tank and you would know whether there is an issue with your main tank or it was just this one fish.

Yeah I did read it’s hard on them so didn’t add much salt , I don’t have a quarantine tank but otherwise I would have, should I get some api stress coat with the aloe Vera in to soothe is injuries if that’s what it is

If you use a product like PRIME, that has the slime coat properties as stress coat so no need to get both.
