taking them out to feed is a good but impractical idea. i feed the pellet food and some greens every now and then. i never feed them any protein except whats is in the reptomin.

I once tried to plant live plants in the tank but they ate them...

the sliders are about 3 inches each and will be moved into a pond next summer.

ANOTHER QUESTION:
what medium combination works best inside a canister filter?
