Hi, I bought 10 pacman frogs a few months ago, and since then they have grown at an amazing rate, now I'm wondering how I determine when my frogs will be ready to breed?

Is it by size like some snakes, or more about age like turtles?

Should I start the breeding cycle when they reach adult size, or should I wait for the first cycling until after they reach, let's say a year or something?

TY for your help.

Andre
