For red severums, check out Atlantic Tropical in Artesia. They have about 15 there from 3" to 5-6" ones. ($10 to $30 I think, but you can always bargain with the guy cuz he's cool.) Also, 405 Tropical in Westminster had some at about 3-4" for $12. If you want a rotkeil red shoulder sev, call up A+ Tropical in San Gabriel. I think they still have a nice one that's about 5" and $25 or $30. And I think a few PetSmart locations have green sevs for $6 if you're looking for those. Good luck.
