Hi! I am a little worried about my AFT's tail, but I hope that I am just being paranoid. He has a little dark spot right on the tip of it. I took some pictures, but it is really hard to see. I'll post what I have. It's just a little dark spot right on the tip, and I am trying to be proactive about it because I have never seen this and don't want it to turn into something bad. Let me know what you think.
