I'm not sure how long I've had them, a couple of months I should think. I've never tried hand feeding them, I just put 6 or so crickets in the tank every few days. I've managed to hold the less shy one a couple of times and he actually doesn't seem too panicked by this, perhaps I should just build on this and get them more used to people?

Oh, the way I know which is which (they're called Bert and Ernie) is that he less shy one (Ernie) is much skinnier. I've actually seen him eat, so I'm not to worried, but I wondered if the difference in body shape might show a difference in gender? I've never heard them call.
