Mating Calls in Very Young ACF?

[mpmistr]

I decided to pick up a fourth ACF, he's very young so I am keeping him in a 10 gallon aquarium until he is large enough to join my three adult female ACF.

Last night I finally heard a Xenopus mating call! He actually kept at it for at least an hour or two and it was pretty cool. I am kind of curious though, this frog is very small, very small maybe only 1 inch tops. He is far too small to join my adult females and would probably get eaten before he hit the substrate. Is it typical for them to start mating calls this early? I believe the froglet is two months old tops, I'm not really concerned here just genuinely curious why they begin mating calls when he is more than likely sexually immature.

He could be older than you think, do you know how old he was at the store? I have a male that was a slow grower and was calling when small, was a year old. He has grown since then, but still my smallest frog.

Pet store had him for 6 weeks, I'm guessing he's about 2 months old. He still has that juvenile look to me. I hope he's not even close to full grown because my other frogs will eat him!! :P

One of the ACFs that I raised earlier this year started calling and amplexing at just under 3 months old when he was about the same size as your new frog. He's been calling every night since. I have no idea why some frogs start doing this so early but I'd love to know.
