mts eat pond snails?

I'm not sure but after a WC today I saw a mts with pond snail in its mouth. The pond was quite small, <1/16 inch, the mts about 1/4 inch. It had the back of the shell picked up off the sand & was moving like it was trying to turn the opening over. The pond had several grains of sand on it's foot (?)

I have seen some empty pond shells but thought they were just being fed less. I introduced the 2 mts recently to help stir up the sand & compete with the pond snails. And yes, I added the pond snails to help eat leftovers & their population could use some reduction. I sometimes feed them to my loaches but they often end up in the filters.

So I'm not really complaining, I just thought it was strange. I wish I'd had time to watch longer, I can't see them now. Anyone see this before?

Yea, I saw that. I was seeing empties before the mts & with only 2 mts vs 30+++ pond snails. These trumpets are less nocturnal than I remember & move pretty fast when thay want.

I've been looking closely at the tiny baby snails but no trumpets yet. You think with live food & leftovers they'd breed up a storm, but it's only been a couple weeks.

I was a little concerned that finding empty shells meant dead animals in the tank & I've had cory troubles in it. Nitrates 5-10 & 0 ammonia but fairly planted.
