Where do fishes go when they die?

Whats the proper mode of burial for a fish? Alec, being his usual insensitive self, thinks we should flush it down the toilet whilst saying the last rites- an option that secretly appeals to all of us, while Naomi, devastated ex fish parent, thinks we should invite people over and hold an all night vigil. Now, i don't want to be mean, but last time she conned me into holding an all night vigil (i think she made me go to Mass, but the reason escapes me) we fell asleep in the back of the church and missed the entire service.
So... choices, choices. Might I suggest a vote?
