First of all, I have the option of bringing home two more WTFs from a customer. They have had them for about three years and the gal bought them for her granddaughter who no longer lives in the state. She just wants them gone from her house. Would four WTFs be too many in a 24x18x18 Exo-Terra terrarium? I would much rather take them and give them a good home instead of letting them just sit at this gal's house.

My second question has to do with moss types. I was looking at either getting Zilla's Beaked Moss or ZooMed's Terrarium Moss to mix in with my substrate (I pulled out all 50lbs. of gravel that was being used as my drainage layer -- realized that it was too heavy to move afterwards). Does anyone have any experience with either of these types of moss? Preferences? Looking at getting leaf litter here in a couple of days from Josh's Frogs to cover my substrate...

Any help would be greatly appreciated!

Thanks!
