What temperature do snails thrive for a Snail Breeding Tank...

Mantis,

My money is on the loaches. I have 5 in my tank and I give them 10-15 baby snails every other day or so (sometimes every day). I have yet to see an egg in that tank. I have put a few large snails in there as well. They haven't fared any better.
 
Not all snails have both reproductive organs, as I stated before if they did they would be asexual. Apple snails actually have intercourse the male snail will "mount" the female. TKOS is right about the fact that most times the snails are impregnated before you buy them.
