I have been working hard on getting him the best, and with time the Ficus grew up a lot (and still is!). I added a few live plants (Hoya Bella, Philodendron Scandens, and the Hibiscus died lol) and a few plastic plants too. To ensure more humidity and comfort i added the live plants, and privacy was obtained from fake plants on the higher border areas.
Since i have two cats wandering all-day long, i made sure to have enough plants to let him hide if he wants to, in the lower and higher areas, while he still has a good opening to watch everything in the room!
I also have a video that i posted on Youtube, but since i am trying to participate in the video contest, i don't know if it's allowed to show it here!
Here is an update of Delko! He is now 11 months old and he seems fine! He had difficulty getting used to my girlfriend and i new appartment, but after 4 or 5 days he has been much better! He now travels at least 6 meters each day on the cords i set up for him. He also has a big and very sunny window next to his enclosure! However, don't worry, the temperature and air flow have been checked to avoid any health problem!
And now this is his new free range setup. It is easily 8 meters long, with a big plant (cissus) in front of a window. In the next few days, i'll add a few other plants too, to make it better for him!
