On a sadder note, Mrs. Badger's betta, Hammy, died today. We got him last winter to celebrate getting through a scary medical procedure. He was really cool, with a lot of personality, always up at the front of the glass mugging for food and attention. His flamboyant personality and his bright blue color reminded Mrs. B of Hamilton in the musical, thus the name. When we first brought him home, he jumped out of his cup while I was setting up his tank and lay on the floor for I don't know how long before we found him. He recovered in less than a day, and we put a poster above his tank that says, "Look around, look around, at how lucky we are to be alive right now."
He occupied every bit of his five gallon cube. Once we put in a bunch of live scuds; it was the best day of his life. He relentlessly hunted them down with obvious enjoyment.
When we got back from our long trip a week ago, he wasn't right. His colors were a little speckly, and he wasn't as active as usual, just sort of hanging around on the surface. The water parameters were good, his keepers hadn't over-fed him, the plants were growing lushly, no obvious disease symptoms except a swelling on the side of his face. My only guess is that the cheap cannon decoration in his tank was releasing toxins, but it was in there for months before we left...
He was a cool fish. Sure wish he had lasted longer.
