Hey! So usually when I walk by my tank or look at it for a quick second, my clownfish run to me like dogs. I just noticed that my black clownfish has one weird scale? It’s like a small clear scale slightly raised off if his left side of his body. I have another clownfish in my tank but he looks perfectly normal. They are both acting normal. I’ve had my tank for a little over a month now and everything has been going smoothly. I tried to grab some pictures of it but he is literally insane and keeps moving lol. Any help is appreciated. If I need to check parameters I can, but my ammonia reader says ammonia is safe. Thanks!
