Just purchased this blue hippo and did not notice this on his dorsal fins! It looks like scaring to me and is only on one side of the fin. It’s not ich or velvet and was wondering if anyone knew exactly what it is! Not sure how I did not see it til I looked at him in the bag with the flashlight on my phone but
He was eating when the guy put food in there also!
