Although he's been gone for awhile now, Kiyoshi deserves some form of special acknowlegement. If I never had him, its very likely I would have never had any of my current fish. He was the one who opened my eyes to betta fish.
I remember falling for him when I saw him- I've never seen a truly pink betta fish. And so far, I have never seen any fish come close to him.
I remember he went peacefully. He had a strange burst of energy before passing due to old age.
Although I miss him, I am proud to have given him a good life. No doubt he's watching from above. ;)
