Red Eyed Tree Frogs in New Mexico!

[Bolisnide]

I stopped into PetCo to pick up some crickets for my white's, and to my surprise they had 5 Red Eyed Tree Frogs! And they were on sale for $29.99!
And, they had a 12x12x18 zoo med frog kit on sale for half off!
I have never seen red eyes in NM!
Well, my addiction got the better of me.. and my husband is now convinced I am a complete frog freak !
I now have 2 of these beauties in a 12x12x18 enclosure.
I need some advice on the enclosure and the frogs.
The enclosure came with frog moss (sphagnum moss), a brick of coco fiber, a terrible fake plant for mounting to the side, some water conditioner and rept-vite.

Here's a photo of their enclosure, thinking of taking out the fake plant on the right as it's a little pokey:



for now, the substrate is the moss which came with the tank, a top that is the coco fiber, and atop that some oak leaf litter I already had on hand. Not really happy with the substrate as it is now and any suggestions are more than welcome. I will eventually do a false bottom like in my white's tank.
There is an exoterra vine, fake branch I had on hand suctioned to the left side of tank, a fake plant in the front left, and that horrible fake plant hanging on the right. There is also a live snake plant in the substrate at the far left hand corner. I will be adding some pothos soon....
Do you think the 12x12.18 is suitable for now? For how long? I will be upgrading to a larger tank when I have more funds in a few months.

I've been keeping humidity at about 80 and the temp currently is about 82 farenheit. Last night the temp was about 74. I have a 40 watt day lamp above the tank, and at night currently nothing. Will probably add a ceramic heat emitter during the cooler months.

Now for the frogs! Both seem fairly healthy, not too skinny and have a nice green color. The pet store said they fed yesterday morning, so I didn't try feeding them last night. I will feed in a glass bowl, and will try that tonight.

They both had a very stressful afternoon being transprted to our house in the country about a 45 min drive, then in a critter keeper until I set up the tank. Moving them into the tank was a little tricky, they are so jumpy and delicate (unlike my sturdy and somewhat chunky white's tree frog). But they made it safely and are now settling in.
They did go into the water bowl last night as there was some coco fiber in the bowl this morning, and are now both asleep.

One is up high in the corner of the tank:


The other is on the substrate below, I'm a little worried about this one on the floor. I nudged him gently with my clean finger this morning to be sure he was still alive, and yes he is. And his color looks ok:




My son and I are sooo excited about these little gorgeous frogs.
Again, any help would be appreciated.
