>>I thought that since pygmies lived on the forest floor that they didn't bask becuase sun didn't reach donw there.the temps would not have a huge difference from once spot to another.
You're right to some degree. Sun does get down there but it is dappled as opposed to large expanses. I find that they bask for a while then move on. My girls seem to bask more than my little guy.
>>Most caresheets i've read say to just have a uvb tube over the top and keep the temps in the low 80s.
It depends where you read. According to AdCham (and I quote):
Lighting: Only a single cool, white fluorescent bulb is required over the length of the tank. Basking and UVB bulbs seem not to be necessary.
But according to Liddy Kammer (breeder) they need some just not as much. I have them in the room with my grow lights so its available if their system needs it - I don't think it will do any harm.
>>anyways a 30 gall seems big for a 1 inch reptile. that will be lots of space for them to cover to get anywhere.....so put the feeding bowl in the middle.
They are currently in a 10 gal. and this will be too small once they get bigger so I have opted to move them now. I think one of my girls is gravid so I don't want to disrupt the eggs once they are laid. If she is not - she will be in time 
Make sure they have plenty of little trees that they can climb up into at night to sleep and have spagum moss on the floor to help with humidity. potho vines are a fav to climb in.
Oh - they have plenty of places to roam, hide, bask, whatever their itsy bitsy heart desire. I do garden design so I get pretty creative with these mini "worlds"
>>you try a creeping fig....its part of the ficus tree group and seems to like to grow up stuff but it makes like a carpet of tiny green leafs...my big jackson loves to sleep on them for some reason
All of mine cling onto a stem when they sleep - it's very sweet 
Thanks for your input!
