Male Samuri Gourami (captive bred), symptoms only include flashing (rubbing his bodies on plants and the leaf litter). This has been going on since his purchase a month and a half ago, the black spots don't seem to be multiplying or reducing. I don't have much knowledge on diseases so I'm turning to reddit for help. I'm guessing it's Black spot disease or natural coloration (I doubt this)

Ph at 4 Ammonia and Nitrates 0

Note that the spots seem to only be persistent on the right side of his body
