Can I keep a female and a male together?
Can I use earthworms from my garden (pesticide free)? (I have fed them to my expensive goldfish breeds without any problems, so I think it's fine)
Should I use a heat pad? NYC, keeping it in the basement where it is warm and humid. It's around 80F in here since it's the spring, and lowers to around 75f at night. If I have to get one, can I wait till the winter?

Also, is this a male?
