blue tongues are pretty cool and if i ever get some spare space, they're definitely on my list
I visited the forum at bluetongueskinks.net for a while to learn more about them, as there are several sub-species with different looks and personality traits
I did learn from people there who had both BTSs and beardies that they're more mellow than beardies
I love my beardie
I'd probably love a bt skink as well
they need about the same amount of space, but I understand that the bts are easier to feed
hope that helps
