Long story short, my poor bannerfish had a horrible case of ich that i finally got under control. Sometime during the treatment, he developed some darkish spots in the middle of his dorsal fin, then the next day the skin on the fin along with the dorsal ray disappeared. He's back to normal now and back in the dt, which he seems VERY happy about. He's still cute with his little knub, but i was wondering if he's gonna be "unique" forever or if you guys think it might grow back. Thanks in advance, i think i attatched a pic of him, let me know if it doesn't work...
