One of my friends who is also a fish enthusiast gave me a beta fish yesterday and I couldn't get him home for about 6 hours plus however long he had him. At first, he seemed very stressed and I got him home as fast as possible, quickly temp acclimated him to an empty planted tank and put him in, I let him rest overnight and the next day he seemed to be doing much better. However, I noticed some black stuff around his gills and just wanted to check if anyone knows if it's serious or just part of his natural coloring. It seems to be puffing out of his gills a little, could it be some kind of ammonia burn?
