I almost bought a 4-5 foot Green Anaconda 15 years ago.
As much as I like them I am glad I didn't, the current gf will not touch snakes so no 10+ footers for me. Besides at adult size I would need half a dozen or more friends willing to help just with habitat cleaning day, the poor thing would have ended up in a zoo due to my inability to keep such an animal in my situation.
I don't care if stores continue selling these I just wish they were much clearer with interested people thinking of getting such animals. If you can properly care for it through out its' entire life more power to you. I cannot and I knew I could not but, that was not due to the store staff indicating potential issues.
