kueluck's Album: The Gray Tree Frog Gang here's a link to my Cope's. I have 3 in one tank. "They" say they are fine alone, but mine usually hang out together, I think it's one of those save in numbers things. I raised them from tads last year. I feed mainly turkish roaches, my neighbor also feeds crickets once in awhile and silk worms. You want a high tank since they live in the trees, no special lighting since they are nocturnal. My tank stays any where from 65 at night to 85 during the day but averages at 76. Humidity runs 40 to 60%. Make sure you have a water dish for them to soak in and DO NOT use tap water that contains chlorine, I use clean rain water or spring water. I use moss on the bottom of the Exo Terra. You don't want them close to blowing air since this will dry them out quickly and have a hard time shedding then. When they shed they look like they are gasping for air or yawning and wipe themselves, pull the skin into their mouths and eat it. There are lots of people here with grays so you'll get lots of info. They are hardy little critters and they are a blast to have around.
