We had a Betta that was nearly the same coloring for several years, his name was Scrubby Bubbles. When he passed away we had a service and made a little grave with a headstone that still reads..."Here lies Scrubby Bubbles...He was a good fish!" He passed right around Halloween and we happened to have a little cardboard coffin that a chocolate Dracula had come in, so he was buried in that. Quite a decent send off for a fish...better than a flush I would say.
