new to fire belly toads

[Pookie]

I just got 5 new fire belly toads. I'm new to the amphibian world but i've had snakes and reptiles for years. My major question is how can i tell the gender of these toads? What does it take to breed them? And how much should i feed the 5 of them at a time and how often? Any sort of information would be great, i keep hearing different answers! Thanks!
