Need Help To Identify New Frog

I have a bio active set up i was hoping to use for red eyed croc skinks but still need to buy light and heat (and a cooling system for summer) but a friend of mine saw it and decided to buy a frog for me, and sinve i dont have another tank right now i put it in the vivarium, but i dont know what kind of frog it is or how to take care of it.
This is it, it developed some kind of black spots on the back. It is maybe half an inch.
The tank is a 55 gal
Temp stays in the low 60s and i keep humidity in the high 80s by misting twice a day with dechlorinated water.
I will buy a heat lamp today or max tomorrow, what wattage would you recommend?
What should i feed it, for now it has been eating the isopods and some centipedes (half its size).

Some pictures of the set up

 

Are you in the southern United States?
It looks like a green phase Ornate Chorus Frog. Pseudacris ornata

 

I live in the southern part of mexico.

thanks it looks more like pseudacris ornata than the hyla cinerea i tought it could be.

Now i will have to do some research on how to care for it

 

A bit late, but i found out what it is, a mountain tree frog (hyla eximia)

 

That would explain why it wasn't in my guide for reptiles and amphibians of the Southeastern United States lol
Glad to hear you found out what it is.

 

Yeah, someone told me that since it is a 55 gal. tank for 5 frogs i could add a crested gecko or a pair of anoles, i have heard it is not recommended to mix species so im not really into it, but out of curiosity. Would it be posible? this is my set up (a few weeks ago, now the plants are bigger)

 

I wouldn't recommend it. It is entirely possible to keep certain animals together without issue for a long time but surprises and accidents do occur.
Another thing about amphibians and especially tree frogs for some reason is their eyes are bigger than their stomachs and they'll often mistake things for food like a keeper's hand or other frogs bigger than them. If you threw some anoles for example in and the frog decided to try and eat one it would likely choke and they would both die.
Here's an image of a tree frog trying to eat an anole almost its own size.
