:vertical surfaces. The bicinctores are doing well. I lost one female to a prolapsed intestine. They are super hyper though. A lot of jumping at the sides of the aquarium and scratching at the glass. I have I think 3.3 maybe 4.2. I think I am going to keep a pair and sell the rest as I work mostly with chuckwallas. I have 2.1 Utah yellow heads collareds I purchased from Will. I think I will eventually sell the extra male. I also have 2.1 C. dickersonae, 5.9 chuckwallas(obesus) and 2.3 San Esteban Island chuckwallas(varius). Nice chucks, I will have to see a NEW pic of them !!
