Bred invertebrate myself,
Posted Aug 20, 2014
This is a true hobby classic. These animals are prized for their typically docile nature and fantastic coloration.
In my experience, B. smithi tends to grow on the slower side, though they make up for that with a longer life span overall. I currently have one female that is over 20 years old.
While they are not really prone to biting, some individuals will flick hairs when disturbed. This isn't a problem for most people, but I do know some that have intense skin reactions from the hairs, so caution should definitely be exercised.
These spiders also have a tendency to eat themselves to death. I've seen many examples of overweight animals (where the abdomen is 2-3 times the size of the carapace). Owners need to exercise restraint with feeding - if these guys become too large, there is a risk of injury and death from falling or from having too much weight pulling on the pedicel (the area that attaches the abdomen portion of the body to the carapace).
These are a great spider for beginners, and are well worth the pricetag. They're hardy, easy to keep, and live a long time, even if you happen to get a male.
