Axolotl Eggs and Heater

[LolaAndDani27]

Hello. This is my first time raising axolotls and so far it is going okay. The eggs have now turned into little axolotls and you can see their gills. I am wanting to speed up the process of their growth and I was wondering if I could put a heater in the tank (at this stage there has been no heater and it is taking a while for them to grow as most days its in the negatives (it's winter where I live). Is it to late to put the heat in the tank as there would be a large temperature change or will the be okay?

Thanks to the people that answer this

No. The temperature change will kill them.
