I'm in the process of planting my 30g hex, and hopefully have it up and running as a frog terrarium in a couple months, but I'm still not sure which kind of frog I want to get. Which will also impact the final terraforming of the terrarium, since if I go for reed frogs I'll only need a pool of water big enough for them to sit in, but if I get big-eyed tree frogs I'll need to make 1/3 of the tank water and make it slightly deeper too. It's so hard to decide.... I'm so used to setting up community aquariums with my fish that having to devote myself to choosing only 1 species for an entire tank is.... a different experience for me. I'm looking at all sorts of frogs, the only thing I know that I want is a frog that is more arboreal than terrestrial (because of the tall tank), and reasonably small (so I can get a few), but other than that my options are wide open.

I've been looking at painted reed frogs (the first ones I saw, and the 'Awwwwww' factor made me want to get into frogs in the first place), which I like because of their small size (I don't know how many I could keep in a 30g, but a fair amount compared to larger frogs) but I'm concerned their call may be a bit high pitched and a group of males would keep me up at night.

Red-eye tree frogs I've been looking at, both because of their markings and their call, but according to the frog lady at my pet store they've been having trouble getting good stock (lots of fatalities in the store... she gets all of her reptiles from captive breeders {win!} so it's not because of fragility associated with being wild-caught) so she hasn't carried them in quite a while. I could get them, but it would be iffy. And aside from the health issue, they're rather large compared to all of the other frogs I'm looking at and I think I would feel bad keeping a frog capable of jumping several meters in a tank only two feet wide.

American green tree frogs.... cute little frogs, with a small croak. One thing that's making me lean towards them is they're pretty inexpensive compared to some of the others. They're probably second or third on my list.

Big-eyed tree frogs, the biggest frog I'm seriously considering. I've heard their croak and it doesn't seem too loud (my mom thinks it sounds like a cat, I think I agree), honestly the sound makes me laugh, and I think they're pretty cute looking. I also thought the white's tree frogs were really cute, but I really don't like their croak so they're out. These guys also get a benefit because they're pretty inexpensive as well, around $15 each where the reed frogs are $36. Dart and mantella frogs I decided against because they retail at around $200 each in my area. I don't really want to spend any more than $40 per frog. I suppose I could mail-order them, but I don't like the idea of putting them through all the stress of shipping. Though I guess they're shipped to the pet store anyways.... maybe if anyone knows a reputable frog breeder online that deals in captive-bred frogs (very important to me nothing is wild-caught) then I could consider going that method.

I've also been thinking about getting bird poop frogs, but I have found only 1 so-so clip of what they sound like and I really don't want to get a bunch, only to have them all become sexually mature and start making too much noise to bear. I was thinking about getting white's tree frogs or milk frogs, but after hearing their calls I figured I didn't want such noisemakers in my living room, so hearing their call before getting them is important to me so I don't wind up having to rehome them a year down the road so I can get a night's sleep.

How many of each frog would I be able to keep? They're going to be kept in a well planted terrarium (large spider plant, large 18" jade plant to climb on, if I can track down info on toxicity I may or may not add an aloe and christmas cactus, plus any plants I get in the future like bromeliads, vines or orchids) with a waterfall/river pouring into a larger pool. I figured if I kept Reed frogs I could keep maybe 8, or even 10? I read somewhere that with big eyed tree frogs you could keep 4 or 5 in a 10g.... would that mean I could keep 12-15 in a 30g? That sounds like an awful lot to me, considering their size. I'd be a lot more comfortable with 6 or 7. For red eyed tree frogs I figured 2, no more than 3.... it just doesn't seem big enough for any more than that. If that. I'm really not sure about keeping them, they seem too big for my tank.... 50-80g seems more appropriate for them.

I've also heard from a few sources that green anoles and house geckos can be kept with certain frogs. I know that big-eyed tree frogs are one of the ones included in that group, but can any of the smaller ones live with them? I wouldn't mind an anole or two running around in the daytime while the frogs are hunkered down until night. As long as no harm will come to either anole or frog, naturally.
