ive got one thats around 2.5". lots of webbing, digging, etc. not quite as defensive as P. murinus, but will fight me if i tread to close to her burrow. also doesnt seem to grow anywhere near as fast as P. murinus. ive had her since early december, and shes molted twice growing a grand total of a half inch.
I've got one that's about 4" and is alot more docile than most I have heard about. Its a burrowing machine and a webbing machine. It has three different entrances to its elaborate series of undergound burrows and it has webbed the heck out of the whole cage area above the substrate. Eats great and easy to take care of. Keep it dry. I rarely ever mist its cage and whenever I fill its small water dish, it tips it over. Cool spider, but don't expect to see too much of it.
