Pretty sure I am going to get flamed but these are the t's I have currently:
A avicularia
A versicolor
P regalis, ornata, fasciata
G rosea, pulchripes
B smithi
T gigas, cupreaus
P irminia, cambridgei
GBB, Blue fang, E murinus
I don't have any heating at all. I mist lightly once or twice a week and most of the bigger T's have waterbowls although 80% tend to bury them in substrate almost instantly.
I feed once a week to every 2 weeks depending on my mood really, also only feed crickets as thats all I have access to where I am based. I do keep their enclosures clean by removing any leftovers or boluses with a LONG tweezer.
I provide the aboreals with upright tanks and the terrestrials with a lot of floor space, generally they all have more than enough substrate.
I don't handle my T's at all, they are there for my viewing pleasure only, nothing to gain for either parties in handling IMO. I know which are the faster species and take precautions when feeding, misting or rehousing. So far I have lost 2 or 3 T's in my 5 years in the hobby using these methods, maybe I'm lucky but the evidence would prove otherwise. Bear in mind I literally lost 2 dwarf slings, they disappeared!!!
What I am trying to say is that the only way to know if you are ready for the more "advanced" species is too take a leap of faith. They are really hardy little buggers actually.
