I have saved some tadpoles from a dried puddle and am taking care of them until they become frogs. But now I am worried of the possibility they could be invasive Cuban tree frogs. Any tips on identifying tadpoles? I had been trying to research but all that tells me is that it is extremely difficult. This is one of the tadpoles it looks like the front legs started to grow. I can’t tell if they are different tadpoles. I can get more pictures if someone is willing to help me!
