Does anyone know what this is. The spot has developed recently. The fish has been not as colorful for awhile now, but eating.

Does this work?

Yes! It looks like either heater burn or an injury.

Keep the water clean and low in nitrates and it should heal. Any chance you have a cycled smaller tank you can move this fish to? If so, you can also add 1 teaspoon salt per gallon to help speed healing.
