What is a proper way to get rid of a dead Betta fish?

You could just flush it down the toilet or throw it away. But I think the proper way to get rid of a dead fish is to give it a funeral. When mine died, I made a little paper box and buried my betta in my garden. Then I put a rock on top. Not only is it nice and sentimental, it's good for your garden. Plus you can visit your fish.
