Like many people, my first was a G. porteri (then rosea). She was a 5" adult female. I could have kept her, but not knowing her age (she was definitely WC), I chose to sell her to a new hobbyist nearly 2 years later. That was in 2010. In 2013, I acquired a much smaller (3.5"+) juvenile at my local pet shop. 7 years later and still no hooks, so I guess the Spider Gods smiled on me and gave me a very long-lived female. She could be anywhere between 10 to 15 years old. Odds are she'll still be around by the time I retire (less than 15 years). Yep, this younger one is still WC, but likely one of the last to be exported out of Chile in my area. As long as I can maintain Ts, I'll always have a G. porteri in my small collection.
Mine was a L. klugi sling. I named him "Verdugo" and I still absolutely love big, fluffy, new world beasties! When I bought him I had done some research on tarantulas beforehand, but had never heard of that species before and didn't really know what I was getting at the time. For some reason I just loved that little fluffy sling and took a gamble. Turns out it was the perfect choice. Active and fast growing with some attitude thrown in the mix. Really ignited my passion for tarantulas.
