How big were they when you bought them? Were they under water as in a fish tank? I think African and dwarf are the same thing if yours were underwater frogs. Yes, they come in albino, too. I've only seen the type I think you have and fire bellies. Some stores occasionally have a bull frog (larger). How long ago did you purchase? If recent, and you have receipt, you might call the store and ask if they are getting in a new shipment and explain you need smaller frogs. Hope this helps.
