ghost shrimp you say? How big do these ghost shrimp get? Would larger polys still consider them food?
Also theres a large pond in the hills above where i live and every year there's a massive tadpole bloom. My question regarding the tadpoles is, are they safe for polys to eat, will the polys eat them? Will polys eat the adult frogs? I figure it depends on if the frogs are toxic or not, but I live up here in Canada, not many things are considered toxic.
EDIT@ GarNiac
No not feeders...well not in the conventional sense. Like a type of small schooling fish that would be present in their native waters. Something that i can just re-stock when they snack on them. Bulk of their diet will still be earthworms pellets silversides and beef heart, but it would be nice to have something living in the tank, just in case one gets hungry, or for some reason I'm unable to feed them for a few days? I have the 6 polys in a planted driftwooded 180, might be nice for them to flex the predatory instincts every once and a while.
