That is a gorgeous corn! Sometimes individual colubrids just have a nasty attitude forever. I had a Texas lucy that would take my face off if she could every time I opened her tub. I had a rat in the tongs ready to shove it in her face for her to bite whether she was hungry or not whenever I opened her tub on cleaning day lol.... And I have my 11 year old Texas lucy male that is sweet enough for kids to hold.
