I know I'm totally not helping, but I can't get video on my phone. :/ And about water quality... I have tested his ammonia and nitrite DAILY since I am cycling his tank. The longest I have ever gone without a water change is three days, as I change my water whenever I get a .25 ppm ammonia reading. I SWEAR, I keep my tank REALLY clean. And it doesn't look at all like the description in the above link... I thought maybe he was tail biting, but the ends have color, and tail biting was described as not having any odd coloring or anything, and I have never seen him do it/chase his tail. But he is acting completely normal, besides the way his fins look. I'm really worried since it doesn't perfectly fit anything...
