Being only a small fish you would probably never find it .
Some very good scavengers ( bristle worms ) make something that small disappear fairly fast .
I've lost 2 sand sifting gobies at different times along with a few shrimp and they are never to be seen again .
Still no noticeable changes with ammonia .
Like you said though every system is different .
