Finding dead fish

[MKLKT]

Honestly in a tank that size I doubt a clown would have much effect. Clean up crew will consume it really quickly. I have a system less than half that (65 + 20 sump) and of the few fish that did die they were eaten in less than an hour. (Bumblebee, Nassarius, etc.)

I personally wouldn't worry about it. You could check the ammonia to make yourself feel better but a healthy system will gloss over a single fish loss. (Especially a 1" fish.)
