Please help me. What is this on my catty? We currently have low salt and copper in treating white spot on discus.

Hi, welcome to the forum.
Please can you tell us the dose rates and duration of the other treatments.
Also current water test results will be useful.
Thanks.

Hi and welcome to the forum

It looks like a graze/ scratch on the bristlenose's nose. Clean water and gravel cleaning should let it heal without any issues.

You can treat white spot by raising the water temperature to 30C and keeping it there for 2 weeks, or at least 1 week after all the white dots have gone. It's safer than using chemicals and if you have discus, the temperature is probably pretty close to 30C anyway.

Don't use heat and chemicals at the same time.

Before you raise the temperature, do a huge water change and gravel clean to remove as many parasites form the tank as you can. Make sure the new water is free of chlorine/ chloramine before it's added to the tank.
Clean the filter too.
Increase aeration to maximise the oxygen level in the water.
Insulate the back and sides of the tank with 1-2 inch thick polystyrene foam.
Have a coverglass on the tank if you don't already have one.

A photo of the whole tank will help. Be careful of what you put in your tank and why you are doing it.
