After doing more research I've decided to have a big tank for a blue tongued skink instead of a small tank for a tegu/savannah. I think overall this is a better choice.
Thanks for the help on the tegu's. I think I found a good site on skinks though.
Oh, sorry for so many questions. >.<
Is anyone familiar with the Hamburg Reptile Show's vendors. Is there anything I should avoid in particular or just use common sense?
