Found the solution to my problem. however the problem solver is a known fish eater as well. I recently adopted a red ear slider and while today cleaning her tank out, I tossed her in the feeder fish tank that is loaded with pond snails and mts alike. well I havnt seen a single snail since she was in there for 2 hours today, all I can find are old dead shells from sometime before today.
I am wondering if smaller red ear sliders would be ok to use for this, the only issue is finding very small red ear sliders.
