Tom's Big Spiders - Tarantulas and Inverts
A podcast devoted to the proper care and upkeep of tarantulas and other inverts. After keeping a G. porteri for over 16 years, I decided that I wanted to add another tarantula to my collection.

Best Tarantula Species to Keep to Gain Experience

When making their wish lists, many hobbyists identify spiders like Old World tarantulas and giant tropicals that they'd like to keep one day, but don't currently feel ready to do so.
