The Crayfish Died

Our crayfish flipped upside down and died. It was sort of a sad thing.

The worst part of it was the smell - it managed to pollute the whole fish tank with a nasty fishy stink and half our house by the time I'd found it dead. So it necessitated a major water change for the remaining fish and a ahead-of-schedule fish tank/pump cleaning.

I'm wondering how it happened. Maybe it was just near the end of it's lifespan? They are supposed to live about 2 years and ours was about that age. Maybe I put in too much fish food? I'd dropped a bunch of watercress at the top of the tank for the fish like usual, except perhaps in a slightly larger volume. The fish were really making short work of it, and putting out a ton of poop, which could have overwhelmed the crayfish.

Anyways, it was sort of gross, but we dealt with it and now we just have the surviving 5 fish that were originally meant for a crayfish snack.
