This is an impressive heavy-bodied species that makes a spectacular display tarantula as it stays out in the open most of the time. Of the large, terrestrial spiders, this is certainly one of the most beautiful. These rather bold creatures begin to have adult coloration early on, making them them look like miniature adults when they are still quite young. They are hardy, easy to care for, and feeding time is always a spectacle!



Giant White Knee Tarantula is a terrestrial tarantula though some do burrow most of them will not. Simply having a hide big enough for it to fit under in your enclosure should be fine. As for size of your enclosure will want to have a 10 to 15 gallon tank. The Brazilian Giant is a poor climber due to its large size therefor it is key to have a tank that is more long and wide then it is tall. The height should be just enough to allow your tarantula to easily flip over should it start a molt. This will prevent your tarantula from climbing up the enclosure and prevent any injuries it might undergo should it fall. A full shallow water dish should also be readily available with fresh clean water at all time. Your substrate should be about 5 – 7cm thick and should be relatively dry. A nice mix of vermiculite/peat moss and coconut fiber should be just fine. As for temperature you will want something between 26 to 28 degrees Celsius with a humidity level of about 70 percent.



Your tarantula will pretty much eat anything from insects to mice. We would recommend a steady feeding of only large crickets, cockroaches, mealworms and superworms.
