We have a male veiled chameleon, solo, in an 80 gallon glass aquarium with a screen top. We had purchased him after being told that the micro ecosystem we were going to create for him in the glass enclosure would work. After the purchase, we heard glass was not good. This was about 8months ago, Pepe the cahmeleon has grown considerably, as food, and any possible light and heating need were addressed, (as far as I can tell). Our problem is this; Pepe was doing great, shedding and growing, shedding and growing, no problems. He was eating crickets and mealworms as offered, and drinking water, both from the waterfall and dish above it. All of a sudden, Pepe is lethargic, and does not eat as much as before. He is currently shedding, but is now not moving much, and just hiding under a bridge in his environment. His eyes are open, and if picked up, will attempt to slowly crawl to higher ground. His coloring is bright, his tail is plump, and when reached for by hand, he "leans out". While there is no obvious cause or visible injury, but we are concerned, as he is acting completly different.
