I have about 20-30 tree frog tadpoles. When I got them they were about 1/4" which was about 1 week ago-2 weeks ago. They are growing quick, everyday it seems like they've gotten a little bit bigger then they were before. I'm not seeing any legs yet on the larger tadpoles or smaller ones but I'm hoping to see some pretty soon. Its my first time working with tree frog tadpoles (had bullfrog tadpoles) so I don't know how to make a metamorphosis tank. Also is it true that I should separate the bigger toads from the smaller ones because it could slow down the processes of the bigger ones hatching. Any ideas or recommendations? Thanks!!!
