never done it and not a senior experienced member/cham owner but id say....possible....yes...easy to do so for correct proper long term care and maintenance...no....
youd basically have to have a zoo or aquarium exhibit, massive amounts of real ground cover with all the little critters that break down solid wastes as well as things to keep them is check so they dont overrun anything..so on an so forth up the food chain with the cham being the top dog, a ton of live plants for air filtration and purification, proper circulation, just having some screen isnt going to cut it, youd have to have fresh air pumped in and the old stale air pumped out...your cham is going to poop, most likely in the water which is going to foul your water and give you constant nitrate and amonia spikes which is bad for the fish which will most likely lead to fish die off which will cause a bigger spike and your cham might want to have a drink or two...
im new to owning chams but ive killed enough fish lol (anyone whos kept fish has killed a few fish lol) to know that maintaining a proper fish set up is a fair amount of work as well as keeping a cham, i worked in the amazon rain forest section and the pacific reef section of the nation aquarium in baltimore and it was no joke how intricate those multiple animal set up were.. looked great from the outside but man...were talking hundred gallon plus sump tanks to keep the water clean from everything that lived on land plants included just to have that "natural" affect...dead bugs..dirt.. poop...shed skin, leaves, the natural bacteria from the animals etc etc none of that mixes well with fish in an enclosed set up..in nature that all gets swept away and broken down constantly...in an enclosed system, youd need massive filtration and a very large sump and skimmer to keep up with it along with routine clockwork maintenance schedule...
for the most part and correct me if im wrong anyone, no one really LIKES maintaining cages we like looking at them..we clean them and maintain them because we have to so our animal is healthy but if it was away to not have to pick up another turd again..keep the animal in top health and never trim prune or pick up a dead leaf.we would just sit back and watch... but the set up your talking about is way more working on it and fixing it than looking at it..
