They may be taods but I am not sure. Just going by the spots on the one and the almost black color of the one that looks most like a tadpole still. I am in the same boat right now, lol. I am trying to figure out what my little tree frog tadpoles are. I hope they are greys, but I won't know until they morph... Lol. Here is a pic of them the day I brought them home (one week ago). The biggest one is ready to morph soon, his back legs are almost fully grown in and has little bumps in the place where his front legs will grow. I am going to post updated pics of them soon. Good luck with the little ones!
