My P. regalis:
I have 4 P. regalis, 2 large 6 1/2" females and 2 smaller slings. They are fast but non aggressive. The only time I have had one go into a threat posture is when I am trying to get them out for a photo or to change cages. They are great constructers and have built some of the most intriquate tube webs and even burrows I have ever seen.
All are great hunters when you sit back and watch them. As soon as I dim the lights and toss in a cricket they start stalking them. All have large apetites and the bigger females have grown at a faster rate than any of my other tarantulas, a good 1/2"(as slings) - 1" each 20 days to a month. The last instar they have grown 1 1/2".
Housing:
I keep them all in critter keepers with about 1" of peat moss for substrate and piece of cork back leaned against the side for them to attach their tube webs to.
I keep the humidity at about 80% with moist substrate and a water dish. I keep the temperature the same for all of my tarantulas about 80-84F.
I often lightly mist around their hide for a source of water as they never drink from their water dish. They will immediately come out and start drinking the droplets.
