Red eyed Tree Frog setup questions

[J Teezy]

Hello, I'm looking into getting a red eyed tree frog. Here are some questions i have

1. What's a good suitable size terrarium for 1-2 (I'll start with one but if it goes well would probably add a 2nd)

I'm looking at the Exo Terra Rainforest Kit medium (18x18x24). Would this be suitable for 1-2 or do i need to get the X Tall model which is 36" tall


2. Fogger vs Mister

in order to provide the humidity what is a better setup for this? A mister or fogger. The mister I've looked at would be the Exo Terra Monsoon Rainfall Misting System. The fogger would be the Zoo med Repti fogger humidifier

Another question would be, if both are suitable choices how would having both workout? I like the fogger just for the visual it creates in the tanks for say showing off to friends, etc. They both add great visuals to a "rainforest" setup

Also, is there some kind of timer that you could put on the mister / fogger that kicks on when humidity drops below a certain point and kicks off once it reaches a certain point?

3. I have a tendancy to travel in the spring - summer for 7-10 days at a time to my families lake house. I'm assuming I would need to have someone who can come over and take care of the frog(s) during that time. If that's not available what kind of temporary home would i need to have for the frog(s) that i can take with me or have at my parents lake house to house them for those days.

4. For heating, what kind light bulbs are needed and typically how long do they need to stay on? All the time? Is it ok to use something like a blue tinted bulb to create a night time (moon light effect) for certain periods through the day (typically at night) to create a nice visual or will the terrarium loose too much heat if it doesn't have a light source giving off heat all the time?

5. What's the best kind of substrate to use for red eye tree frogs and how much should you put in? (I plan to decorate with the fake plants and jungle vines that come in the kit)
