B. hamorii are very easy to raise, if you ever decide to look for one, try searching using the scientific name, for the reason I'm about to state.
1. Always use scientific names when it comes to tarantulas. For example: red knee could describe many different species, same goes for the common name red rump and many others.
2. If breeding, do NOT hybridize. Breeding tarantulas is very different from breeding snakes. If you breed a pied ball python to a mojave you get other morphs of the same species, right? With tarantulas it doesn't work that way. If you breed acB. hamorii to a B. emilia, you may get a sac, but it will likely be infertile, if you do manage to get a sling that makes it, it will have features of both, but you will have tainted the bloodlines, not to mention you won't be able to sell it, as hybrids are worth less than a grain of salt money wise. Breeding pure tarantulas to others of the same species is not only good for the hobby, but it is also good for the species.
