How's setup look? Opinions?

Got this guy about a month ago he's in a 20gallon for now. This is his current setup, to many leaves/branches? The purple vines are wrapped around two ramps that are attached to a ledge, have three hides on ground level, and a third ramp on the other end of the cage. He has an open space by the food, and all under the purple leaves is open ground. Everything gets fully misted in the morning fully dries during the day, then a light mist at night. Have yet to see him eat. He must eat at night (I hope) he's holding weight, but not really gaining. Holding at 15-17 grams highest has been 18. Past few days he's been holding at 16, I Started weighing him daily in the past week. I have him lick food off my finger, so I know he's at least getting something, and I give him a pea size bit of this supplement fruit paste that the lady talked us into every 3 or 4 days. Water I'm worried about to as same I don't see him drink. When I mist I drip a lil on his head so he licks it off, and I have seen him licking off the walls of the glass. I put him in a bath of lukewarm water now and then as a hope he would take a sip while in there. All the research I have done I can't find an answer as to how often they feed, and how much water they need to stay Healthy. He is doing well active when held climbs up to shoulder to get a good look around. Moves around the cage at night as he's always in a dif spot in the morning than he was at night, so I guess that a good sign not acting lethargic, very active in the tub lol. Posted on other forums, but don't really get any answers. Thanks for your time.

Looks pretty good with lots of nice hiding spots. When he gets more full-sized he may have trouble staying on the plants. My gargs have beaten up all my real plants and are currently doing very well on 2 big slabs of cork bark and a nice wavy piece of liana wood. Try not to worry about his eating and drinking. As long as the garg is active and not visibly losing weight he's fine. I don't think I saw my (now 8 year old) crestie eat or drink at all for the first year or so, but he must have been. Just keep misting, offering CGD, and try not to worry.
