That terrarium seems to be perfect for the species you wish to house. don't be too concerned for the fall as this does happen often when arachnids are active during the night and also remember you have some nice peat moss as a soft landing although they are terrestrial they like to climb so don't limit that too much. The only real time when they will slip from the glass is when they are almost in premolt. The 2 species you have mentioned also are T's that like to be in the open and not really hide but some do. I'm sure the T will love its new enclosure. regards R
I really like this, as an arboreal set-up! May I ask where you found this? I think my Pink-Toe would love it!
-laMort. Tarantulas have an open respiratory system so require very little oxygen in the terrarium, but just watch humidity and temp and allow some cross ventilation which is gud. I suggest u gauge the temp and humidity as this shout always be done as remember there are different species of tarantulas which have different habitat requirements, but always refer to a care sheet as that is the ideal requirements always suggested and the data is mostly captured by scientists in the field. Dnt always listen to ppl that have a negative opinion trust me they the ones that always make the mistakes!!!!! Just make sure there is fresh oxygen exchange and watch out for fungus then the air will be stale and humidity a bit high.
