What a mess! I hope you can convince this person to make some changes !
It is a "disaster waiting to happen" It's sad. It's actually, abusive !
It's a brew of tons of bugs, germs , stress, fungus, parasites, and bacteria ....all have been exposed to crossed contamination as a result of having kept them together!

For proper care , now. Each frog should be quarantined ( for 60 days ) , separately, and have fecal samples sent to a Vet to test for parasites.

Lija and Bill are right about height and size !
For example----I have ( which I consider max) 4 red eyed tree frogs in one enclosure and 5 black eyed tree frogs in another---these tanks are each Exo 36" H x36 W x 18 D

You might find some differing opinions on mixing the first three species, but I'm not sure what would possess someone to think it's a good idea to put a tropical frog like a red-yes in with those first three North American species. Different climates! I don't know much about the white lipped, except they get huge as mentioned. That alone should put them in a cage of their own.

I have read people having success with communal housing for Grays, Hyla versicolor, and American Greens, Hyla cinerea (for the record mine are housed seperately). Also Grays with Barkers, Hyla gratiosa. Barkers and American Greens will also readily interbreed in the wild, so ehh. There's no way I'd put them all together in a 40 gallon though, it would have to be a monster tank before I considered trying it. Like big enough to fit in comfortable myself.

And yes, feed more frequently. Especially if they're all young. But less mealworms, they're not really an awesome food source.

If they were my frogs, each would have it's own 20L vertical conversions. Remember, tree frogs need more air space than land mass. Lija, i read the post like 3 times before i caught it

Knowing you, I'm sure you mean 20gallon tanks, but thought I'd clarify.
