We got my wife a betta. Won't go into the whole story, but it's a special fish. I know better than to buy a fish that doesn't have a tank set up yet; in this case I made an exception. Today while I was setting up his tank, I had him in a cup. I haven't really slept in about three nights, lots of multi-hour driving and extremely stressful time in hospitals. I guess I can chalk it up to that, but I had Mrs. Badger's special betta in a cup, uncovered. I know better than that, too. Sometime while I was working on the tank, he decided to go for a walk. I found him on the floor, still struggling, skin partly dried out, alive but just barely. He's in the tank now, resting on a leaf, not looking great. I sure am going to feel terrible if he dies. Hope he makes it.
