I had an embarassment of riches this past season...8 different species of eggs, and only 5 egg tanks, that's all I could set up. After a while I just started throwing eggs randomly into two tanks (three of the tanks were species-specific and the last two got all the rest!) . I've managed to figure out what everything else is. So can anyone tell me if these would be T. dobrogicus larvae or T. karelinii larvae? Or both? Last year and this year my dobro eggs didn't seem fertile and I didn't get any, this year I thought the karelinii male was too young to mate. Obviously at least one of them was successful. The black ones I'm almost sure are Paramesotriton chinensis.
