Re: Need ideas for a skyscraper tank with no background
Shucks, I didn't even think about cork. It's lightweight, plants can grow off it, easy to assemble and stick together.
I don't know enough about geckos to speak of habitat needs, but I have been told crested geckos need some shade from the level of light that is usually used to grow tropical plants like Neoregelia in frog vivs. I don't know whether or not that translates to day geckos, too.
I don't know whether the photos you linked are similar to what you are going to get / use, but Josh's Frogs has a guide for making a branching cork tree by using PVC piping to connect cork rounds. That probably isn't the look you're aiming for, but it's a neat idea, in case you are very interested in cork-related creativity.
