Most of my fish that have died have ended up getting flushed, except for my last one... My last fish(a clown fish) that died went missing for 3 weeks before I figured out what happened to him. I looked and looked, eventually figuring something must have eaten him when I couldn't find him. One day, however, as I was moving some of the supplies around underneath my tank, I picked up my fish net. Inside was a mummefied clownfish! He had full color, was not rotted, just was a little dried up fish... It's been another month now, and he's still on my mantle....
