Grammostola pulchripes (Chaco Golden Knee Tarantula) MALEGrammostola pulchripes (Chaco Golden Knee Tarantula) for sale This docile species featured a gorgeous gold striping coloration down the legs creating an awesome display animal. This has been a hobby classic for some years now and was perhaps one of the first docile species in the hobby that featured a different color than the typical browns, orange and reds we see in many docile species. Definitely a great option if you love docile species with color!
