Just finished up my juvenile p.metallica enclosure. I have a larger piece of cork bark that I will also be adding to the front side of the enclosure for added climbing room.
I currently have a bromeliad, two fern clippings, moss covering the back wall (difficult to see) and the plant on the left I am not sure. There are probably better plants that can suit the husbandry needs of a P.metallica more but I didn't want to purchase new plants and thought I would give ones from my dart frog enclosures a chance.Looks great! What plant species do you have in there currently?
