When Turtle (my betta) died I put him in a tiny cloth drawstring pouch, about the size of the palm of a hand. Then, I dug a hole big enough to put the little pouch in without bending it. My mom and I had a sip of wine to toast him, then she poured a bit over Turtle's pouch. I gently put the soil over him. After, I put a bunch of his gravel over the grave to form a little mound. Right on top of that, his rock. It may have been to much, but I loved him. He is buried right next to this beautiful tree with long extended branches. It produces berries in the Spring so it gets really pretty with all the birds and squirrels. I think it is a good place, back with nature and other little creatures.
