you could use food to lure him out onto said branch. good luck staying out of his reach though. that tongue is longer than you'd think lol. having him stressed to the point of biting is obviously not a good idea so I'd make that an absolute last resort
there are just new things in his environment. like moving his home this is new to him and takes adjusting. also you need the calcium without d3 which should be used everday
personally I wouldn't use it, but if it'll get you by for a day or two it would be fine to use. I'm not saying that a light tint of blue to their light would affect them, I just personally use white light basking bulbs. definitely don't want a red one though.
as long as one of them is a uvb bulb (probably a coil bulb) and the other is a natural light basking bulb (not red or any other color) you are good to go on the light situation. when he is sitting on a branch at the top he is basking to absorb uvb and heat. this is normal. he is new to the...
idk about the spot. to be honest it doesn't look good but It can't be seen very clearly in the pic. if it's as bad as it looks you may wanna consider getting him to a vet asap. their health is very touchy.
there is a safe plant list that can be found on this site and by a Internet search for safe plants for chameleons. I have pothos, schleffera, and hibiscus plants. if the plants aren't aloud to dry they can grow mold in the roots. some plants themselves are toxic to chams not that they COULD grow...
yea it sounds as if he hasn't a clue what he's talking about. a 75 watt basking bulb should do the trick. their basking spot you don't want more than 95° and to make sure you give him places to hide to cool off if necessary
live plants are another that will help. the supplementing I use calcium without d3 everyday and a vitamin with d3 once every two weeks. my guys eat pretty much everything but mainly crickets or dubia.
first step is to get rid of the red light and get a basking bulb asap. also are you using a uvb bulb? if not that's a big part of the issue. also the bubble fountain is nothing more than a decoration, your cham is way more Ikely to drink from a dripper or off of your plants
my male veiled cham gets darker when it's windy outside and he doesn't have anywhere to get out of the wind. usually he's bright yellow and greens. could be he's just a princess too (y)
defiantly not a good idea. to find a cham sitter via friends, family, local breeder, veterinarian, somebody. that is alot of stress to subject a young cham to.
Maybe start with two sides and see how that does. I covered two sides of my 24x24x48 and helped alot and the three open sides left for plenty of air flow while maintaining my humidity
idk about the fountain unless it's mostly for decoration. a misting system if possible would be a better investment. chams are more likely to drink off of leaves than from a fountain.
