i just got three green anoles and i have them in a tank that stays 80% humidity and i still found two of them in my pound on a log soaking. i watched them longer and noticed that they were trying to shed. even though my tank has the humidity that they need they still like to "take a dip" before they shed.
with mine i have a little fish pound and i found that mine like to let the fish nibble on their bodies. i have found that they have done this each time right before they shed.
