Hello Magdalena! Welcome to FF! Congratulations on the baby on the way. I have been raising tadpoles and it is really fun. If you ever have questions, feel free to ask. I did find a chart that was (kind of) helpful in id'ing...it at least gives you a bit of an idea. http://www.trentu.ca/biology/berrill...ationTable.htm I was able to id our first round of tads as toads according to that. I am still waiting to see what my second round of mystery tads are, plus I ordered a couple more mystery ones off of ebay haha. Good luck!
