I recently rescued i tadpole from a feeder fish tank, that i think is in the Rana species, but not sure exacty. It is a little under 3 inches long and is brown with tiny black spots all over. It looks just like the one in this pic at http://gallery.pethobbyist.com/index.pl?photo=48423&size=big but mine has little 1/4 inch legs. I hope it is a norhtern leo because i have had a great one (a male) for 3 years. Please tell me what you think this tadpole is and i was wondering also when i need to put something in the water for it to get out.
Thank you
