Ok we go to the show every month without fail lol. You will know us if you see us we are the paramedic couple walking around as we have to work after the show lol. Anyway the previous poster was pretty spot on male albinos are usually between 300-350 and females 350-400. You can usually find the red tails around 50 sometimes a little less sometimes a little more. Lastly, spiders are around 125 for a male and 175 for females. Now the good thing about the spiders is that those are a little more established or at least what I have seen at the show are. What I have seen usually runs around 200-300 grams. Hope this helps and if you see two male and female medic walkin around the show say hi! We are usually there from 9-1130. Hope this helps good luck!
