Awww, what a cutie! And BM, I think you've started a movement here... you totally rock. Everyone go to their local Walmart and look out for fish with their tails cut off!!
Oh, and Tailless-Joe is doing great! (He's bettabelieveit's and my tailless dude from Walmart) His regrowth is looking really good. So don't worry, his fins should grow back great. All we used is salt and water.
Like, BM has told me. If it comes to the point where salt and heat don't work, Melafix isn't going to fix it either.
