You can see the front legs through the skin a few days before they POP out!Their just OUT one day in full size!So if you dont see them under the skin it appears they grow OVERNIGHT !!!You can speed up their growth to about 8 months with warm water and lots of food,but some no matter what will take years.If you have a lot together at some point they start killing each other off with a hormonal reliese of some kind.They have their population dynamics all planed in advance.Once frogs house according to size or GULP says one to another 1/5th of a gram less.We gut load crickets on tortoise chow a few days before feeding.I've got one froged out and about 20 to go of the albino morph.Your going to love them.Vic Morgan
