I used to have a red eye, he was awesome!
As far as them making noise, only the males call(which I had).
It was an amazing little chirp which was not heard too often.
You need to spray them down and keep a 1/2- 2/3s of the aquarium top covered(over a screen top of course).
Also, to keep a good ambient temp in the tank,put a submersible heater in a jar of water with some screening over it and he should fair well(given the fact that the temp in your home doesn't get to cold either).
They sleep all day so expect not to see him hopping about till you get home from work.
