How long have you had them?

I've had them for a couple of months, like 6-7.

How old are they?

Less than 2 years old about close there.

How do you know they are male & female?

My Gut feeling... Duh! sigh... Well of course I bought it from a breeder and had a vet check it. I wouldn't claim it's male and female if I'm not 100% sure.

Do you keep the temperatures and lighting schedules the same year round?

Yes
