Sound like my day geckos on steroids
Would I could gather from a quick google search and my own online research for my Malagasy residents.
1) you should house it in a good sized terrarium, 36x36x18, for best effect.
2) Temps should be easy to attain, they seem to do well at intermediate temps...if you are comfortable, they are. Same with humidity, 50%-70% seems right. A full screen top and spraying down a couple times a week should be adequate.
3) Large crickets, beetles, mealworms, etc. should be taken pretty freely
I have always been a proponent of naturalistic, planted terraria. It just showcases the animal at its best.

I would read as much as possible on google...and the accept that there really isn't much out there. I have lined-day geckos and bronze backed mantellas, both are occasionally available...but they seem on the wane as far as popularity. I also grow orchids that are Malagasy....all are in the same enclosure. I researched the conditions, made some educated guesses, a few tweaks...all seem to be doing fairly well. I continue to evaluate and adjust. You will likely do the same...enjoy the journey....then find a female.....
