I am concerned that my anoles are staying brown most of the time. Or they are green with brown. I just took them all out the other day, cleaned the cage and rearranged. I have 7 in the tank. The tank measures 24" long x 12.5" deep x 18" high. Is this big enough or too small. Or do I have too many males and not enough females or what is it? I do see some dewlaping during the day and moving. I also have a Bahaman anole as well in there. Should I get a bigger tank? Get more females? Or leave them be. Oh, the tank is staying around 90F during the day and havent monitored it at night. I also recently added a waterfall for them to drink from and to add humidity to the tank. Your help is appreciated.
