Very sorry for your loss. I think you should give yourself credit in the fact you kept him since 2005. I understand as much as the next guy how hard it is to come down and see your fish not swimming around. But truly what an incredible feat to keep a Sanchezi for that long. I feel as though with some wild caught fish especially piranhas and other characin, it is very rare to see them die of old age (assuming back in 2005 sanchezi were still coming from wild). Incredible regardless.
