An American tree frog. I have him in a 75 gal w/2 anoles, 2 geckoes, and a texas collared lizard. The frog has his little hangout spot. It was previously used by a baby wd. He is doing fine so far. His name is Chevy.

The collard lizard needs it DRY and hot the others need it humid which is exactly what the collard doesnt need.
The collard will also when big enough eat them.

Ouch. So far none of my lizards havef eaten each other. I've had the treefrog for a week. Schrade, my collared, hs been in my 75 and has been functioning normally. eating, drinking etc. One half of the tank is wet and the other half is dry.

mixing species is really not a good idea in 99% of cases. diseases break out more often and there will be problems when they meet at the water dish. I would put the frog in a 20 gal minimum tank alone.

My friend has had 3 anoles and 2 house geckos and 2 green treefrogs together for 2 years in a 55 gallon tank so I am not saying it cant be done tho ofcourse I understand why many wouldnt.
Anoles,house geckos and green treefrogs need the same type of enviroment tho ofcourse anoles need to bask in hot area and the other two just avoid that area but they all need it moist,humid and they wont eat each other unless you have big Cuban treefrogs or other big treefrog types.
Collard lizards however do eat lizards in the wild and will get big enough to eat everything you keep in that tank and again humidity which your other animals need isnt good for them.
Why not just get the collard his own tank a desert style set up than add more branches,plants and mist a couple times a day and keep them in the 75.

I don't consider 2 years with no problems a success. there are exceptions to every rule and yes those animals do have similar care requirements which does help. one thing you forgot to mention is that frogs from Indonesia and frogs from the Amazon have similar care too but you definitely don't mix those species. they don't know how the other species react. besides, even if these animals are from the same area doesn't mean they should be mixed. in the wild they tolerate each other mostly because they have alot more room to move/hide than in a 55 gal tank. I know alot of people won't agree with this post. until I gave my animals away a few years ago when I went overseas I had approx 20 frogs in 11 aquariums, all of them over 5 years and many over 10 years and only one tank was mixed. this tank had firebelly toads and 'chubby'frogs (Malaysian narrow mouth toads) and they were all 11-12 years old. I don't know if they are alive now but I wouldn't say anything about those two species being mixed as long as the tank is big enough. a normal 20 gal tank is too small for mixing, period. I can only comment on my experience and when I tried mixed tanks and bare setups there were problems. Single species (single frog better) naturalistic setups are the best way to go.

I agree with your post. My friends anoles,house geckos and green treefrogs were all caught in Miami her porch and doing very well but granted same area doesnt mean you mix in a 55 gallon tank or at all.
His combo of anole,house gecko and green treefrog (if green treefrog) I feel a fine combo esp in 75 gallon tank.
I am amazed you were able to keep firebelly toads with Malaysian toads that combo I would have never thought would be safe. Due to toxins and the fact that would have thought the much bigger Malaysian toads would have tried to eat the fire bellys or stressed them out due to size.
I looked into them but had a few outside a hotel I stayed at in Malaysia that was by a pond and the males were just way to loud.
