Welcome to the site. My 3 Grays are pretty inactive lately too as it gets colder.

[Kurt]

Welcome aboard. If you have not already read the gray treefrog care article, then please do so and enjoy.

[Tom Highum]

Welcome. Ask any questions you have and don't be shy. Also have you seen Kurt's Meet the frog articles? They are grand.

[Kurt]

Thank you.

Since I've only had these guys a short time, am really not sure what is normal...glad to know that their slowing down is probably normal. Do you provide a heat source for yours? I am using a 60 watt red nightlight (reptile bulb) during the day, and turn it off at night. I hate to admit this, because a lot of people may frown ~ but these guys originated from our lake, and we took them home with us (I let my kids convince me I was saving them from certain death from predators!). Both were brilliant green, one turned "gray" with dark toad markings within a couple of days, and the other had maintained his color until this week, and has now suddenly changed gray as well, no dark markings though. Is there anything I can do to encourage the green coloring to return? I have green paper under their aquarium and on the back side of it and some fake green plants inside. Do you know of anything else I could try? Was thinking of getting some of that reptile carpet that is very green. They spend most of the day hiding under a hollowed out tree log.

Mine are gray most of the time, occasionally getting their pattern back. Sometimes one of my males turns green on top. I believe colour is partly based on their background and partly on their mood. Mine are pretty tame - all feed from forceps and my female will sit on my hand and take food from the other. I don't heat mine and they just have a normal fluorescent bulb during the day time. None of mine hide - they spend their days sitting in the branches in plain sight.

Maybe if you used a brighter light source, fluorescent (won't burn them)
Could it be that they don't like their diet or want sunlight?

[Kurt]

I don't think brighter light is the solution, Hyla versicolor/chrysoscelis is predominately nocturnal. So a bright light will not be appreciated too much.

[Tom Highum]

Hmm then why do you guys think they are not so green in captivity?

The heat light was just introduced last weekend. So that was well after Wilbert "changed". They are located in an area where the tank does get a lot of natural light during the day. I have been feeding them crickets (feed the crickets carrots, potato, apple). Maybe the color thing is just something I won't be able to understand. But if anyone has any ideas, please let me know. Thanks.

Mood and surroundings dictate color. Grays do turn green from time to time captivity. Mine used to turn gray with pale green markings. Very cool. They loooked like lichen covered treebark.
