I am a fan of the Peruvian Lasiodorides striatus. A seven inch female is impressive, especially with their massive carapaces. Like a giant Aphonopelma seemanni. Some specimens have purple around the eyes.
I keep mine in well-ventilated sweater boxes with several inches of moist soil, a large cork slab leaning on the side of the cage, & a good sized water bowl. They don't seem to be much into digging. Mine are usually out in the open, often on top of the cork (a habit shared with Lasiodora parahybana). Water bowls frequently have soil in them, tracked in from the feet of the wandering spiders.
To me they seem kind of lumbering & deliberate; sometimes aggressive. Rarely do they try to run out of cages, & if they do, it won't be the mad dash of many other South American terrestrials. They can be stubborn too, & have the power to get their own way. Appetites are not as much as I would expect from a spider this size. Temperaments are very different from Pamphobeteus, (which are fast, nervous, & savagely attack their prey). Regardless, striatus definately are not to be trusted, with those huge chelicerae & fangs.
Males have more color on the carapace, & are more slender, but otherwise similar. The additional carapace color is evident a shed or two before maturity. Egg sacs contain large numbers of small spiderlings, also like Lasiodora.
This is a species that I highly recommend. There aren't that many tarantulas that hit a true 7 inches (front to back, straight, same side). Striatus has attractive stripes to boot. Big, beautiful, & easy to work with. Should be popular in the hobby for many years.
