My newest rescue betta, Luke Seaswimmer (I got him on May fourth, Star Wars day, so I thought it fit) passed away last night. When I picked him up from the pet store, he appeared to have really bad fin rot, which I figured out yesterday was actually columnaris. He was being treated and improving, but then took a turn for the worse on Sunday. I was surprised he made it as long as he did in his condition, but he was a fighter and was determined. Unfortunately he didn't make it, but his will to live was incredible and was a great inspiration to me. Rest in peace little buddy.
