New Baby Axolotl

I have a beautiful axolotle called Nessie. He is black, about 12 months old, and 17cm long. He is very cute and active. I get so much enjoyment from watching Nessie's antics, that I recently decided to start looking around for a potential wife for him. I looked around at a few pet shops, but didn't find any suitable candidates, ie a healthy and happy looking female of breeding age/size. I eventually came across a tank with a male axolotl, and many eggs! I could see the babies within the eggs moving! Apparently the female had recently been sold. The pet shop kindly agreed to sell me the artificial coral piece, in the tank, that had some eggs attached. They also sold me some frozen micro worms to feed them on. I knew from previous reading that axolotl larvae require live food, but bought the frozen food as back up. I brought my precious cargo home to the surprise of my children. My ten year old daughter commented that I seemed to have missed a step in my breeding plans for Nessie! I found nine eggs with live babies within them. I put each into a small separate jar. So far four have hatched, they are three days old at present. The other five are still alive within their eggs. I keep checking the 'late developers' for signs of life. They occasionally do triple back flips within their eggs, Olympic stuff!
