I think it is a bit ambitious, but I feel like I've learned quite a bit from my preliminary builds to help me construct this. Plus lots of reading lol.
If you ever find Pinnatum, I'd love to get a cutting sent over. They're in the Exotic Angels selection from Costa Farms, so I keep checking Wal-Mart's. I got a Pearls and Jade a few days ago, though. Not like checking doesn't still pay off. I made some posts on Gardenweb and Dave's Garden recently looking for the plant. No results yet.
As for the orchid, there are a few other possible orchids I could get as well. I'm glad to hear they aren't overly troublesome. I think one problem I remember reading about is they need additional nutrition to bloom, and tou can't spray them with nutrients in the frog's tank safely.
Even if it wont bloom and it just sits there, that's cool. I figured I'd plant it in a hollow cork log filled with orchid bark. I'm planning to read more about the care of the orchid before getting it, rather than just the national origin lol
