I have an idea of somewhere between a 20gal minimum for 1-3 (considering using my old bearded dragon tank 40gal breeder dimension that's been empty for some time, but it's longer and not much room to go up), but I want to know what experienced owners would recommend before I begin planning anything. Feel free to comment on anything you would recommend for a good setup, I'll be saving the info (I always make a notebook of sorts before bringing a new species home).
I also have been reading up on arrangements within the tank. A lot of people seem to like the lower area being either an inch of water or an aquarium with climbing space and a platform, but I've heard they're not strong swimmers and would be afraid of them drowning. Is there any point to this setup that is beneficial for the frog, besides helping humidity levels? I've also heard of the half and half, with a split bottom of a couple inches of water on one side with substrate on the other and still, adequate climbing space. I like that option best, but not sure if I want to mess with the acrylic barrier. I'm really on the fence right now.
It won't be a rush to get anything done or make any decisions since most of this will come probably after I move, and I have no idea when I'm moving yet. I don't have the space now, and the tanks I have (20gal and 40gal which I will be using for future reptiles / amphibians) are out in my shed collecting dust while I figure things out.
Last couple things, the 40gal IS disinfected and will be again. It also does hold water. I had fish in it when I was running my aquatics rescue and it did great. I also want opinions on heat lamps, because I haven't seen much about it and it sounds like a bad idea for an amphibian. Danger of drying out and killing them, plus water evaporating into the lamp. Accidentally moved my beardie's heat lamp over his water bowl once and now if you plug it up the whole house loses power. Sooo... in a humid, tropical tank? Bad idea, right? So how would I keep temperatures right?
EDIT: Also, do they enjoy being in groups (of the same size, of course)? Or does it not really matter?
