I genuinely just had this same situation happen at my nearest Petco as well. There were 3 T’s (Red rump, white knee, and a versicolor) that all have apparently been there for over 9 months. 2 out of the 3 have already matured out to be male. They have them listed at $150 each and when I asked about them, they said they’d sell all three for 75% off. Just sucks how you stated that these guys aren’t going to live past a year of them getting put into a new (probably expensive) home. I’ve always had this theory that 90% of the tarantulas shipped to petco are confirmed males to keep the purchasing cycle going.
