Hi, I started out with 6 ghosts, all well fed, but over the last 4 days, 2 of them have gone missing in a 20*20*30 terra. My other ghosts haven't eaten them as they don't get any fatter, I think the ones responsible are my springtails. Is this possible? I mean they are so tiny, would they ever attack a living creature? And by disappearing, I really mean disappearing, there is not a single thing left of them. It's like they never even walked around there...
