Not the largest one I've had but she's still growing. A while back I had a female that I got from Swift as and adult and she came pretty close to if not right at 8 inches. This is a guesstimate as I never got a ruler right on her but had to get it close and eyeball it.
Philip, what do you think about the P.ornata? I have just recently started to expand my tarantula collection to include some of the Pokies and I purchased a one inch Poecilotheria ornata sling..she is quite leggy and appears to blend in with the substrate very well in the deli-cup I have her in at this time...what do you recommend as for temp and humidity levels for the Pokes?
I think ornata is a great species. Personally I love them.
As far as temp and humidity goes all my Ts are kept at around 80 degrees and I don't measure or really worry about the humidity except to keep water available in a dish at all times except for slings in vials which I mist once per week.
