Thanks for the feedback.
Well I spent Saturday planting the terrarium, and Sunday making a cover for the tube that could also support an overhead light.
The temperature is stable straight away, as is the humidity.
I seem to be able to vary both enviromental variables quite easilly, so I should be able to get it just right.
I ended up planting a fairly mature Ficus Moclame, giving some real height until the other two grow, and a young Ficus Benjamina right next to it, leaves hanging over the water.
I put the peace Lilly on the other side of the waterfall, with it's leaves also hanging over.
I'm going to run the terrarium for a week before getting flies,
let them hatch for a week and then get the frogs.

I agree with your sentiment about the waterfall.
The bottom reservoir is completely inaccessible, of that I'm sure.
The one half way down does have a gap there, and it's big enough for a young RETF to fit through, possibly.
I'm going to consider what to do about it... I may put a *very* fine cloth mesh in there, but that would make removing the top half of waterfall for feeding quite hard.
The fogger is in there, so it's very important the frog doesn't get in there - lest he put something on the membrane and burned himself.
I also found that the fogger dramatically raised the water temperature if left on too long. I think I'll have it on for 15 minute intervals only, and only a few times during the day/night.
Any feedback on the terrarium would be appreciated.
Thanks
Gareth
