I have mystery snails in with my fry, and I just saw the most horrendous thing ever. I was hanging out watching my fry, and one of them was picking on a mystery snail. I've seen my fry do this a lot actually, because the snails will have BBS eggs stuck on them sometimes, so the fry will pick at them.
Well, the snail snapped its little door shut ON THE FRYS HEAD. The fry was stuck with his head pinned inside of the snails shell, tail waggling around trying to break free. When the snail finally released the fry, he swam straight to the surface and just sat there. I'm not sure if he's injured enough to cause death, but his head looks a bit red and irritated.
The fry was a good sized one, he is about a half inch long and is one month old. Poor guy. Just wanted to warn everyone! I'm contemplating taking the snails out now...I was so freaked out seeing that and I don't want to see it ever again!
