Most died fish will be lucky to live a year, although 3-6 months is more like it.
Personally, I'm with RockabillyChick on this, I prefer the real fish. Personally, the most unnatural fish I'll ever keep is either fancy guppys or viel-tailed bettas (this is completely true, I'm keeping both of them right now).
As for all this crossbreeding like blood parrots, flower horns, etc, I am strongly against it. I don't want real fish to end up being a rarity at some point in time. If any of my fish were to crossbreed on there own, the eggs would be destroyed or the fry euthanized regardless if the fish can function or not, and nobody would be informed of the crossbreed, to prevent somebdy else from attempting to crossbreed those species.
Ditto for genetically altered and died fish such as "glo-fish" and "painted glassfish".
