Fin rot?? help

[Mengo]

My panda cory recently got a tail injury and it looked like some fungus was growing on it. I put him in a quarantine tank with meth blue. It's the second day and it seems to have become worse. The top part of the tail has become white and i notice a bit of internal bleeding.

Looks like saproleniasis a type of fungal infection you can use methylene blue and aquarium salt 1 table spoon for 3 gallons start at 1 table spoon for 5 gallons and gradually increase it to 1 table spoon for 3 gallons or you can treat with ick X and aquarium salt both are effective treatment for this type of fungal infection @Mengo
