For 3 straight years, I have been gathering Eastern Tiger salamander eggs and raising them to the end of summer. After 2-3 weeks of age, which puts them at 0.75" in length, I cut up blackworms and feed them this until they get to 1.5"- change them over to small cut worms.
My babies are 7.5 weeks old and are nearing 3" in length and are feed morning and evening small worms. They will transform in mid-August usually 5-6".
I take pictures and then release them in Sept or early October when heavy rains are predicted.
Hope this helps. Good luck!
