I was worried at first that he was dark because he was cold (long story about how I got them, but the darker one spent the night outside before I adopted them so I just assumed he was stressed and cold).

Anyway, great looking frogs you have! Glad they made it through that!
Hi Shlee,
Thank you.
Yes.. the last photo .......is a male .... A moreletii ( black eyed tree frog).

There are NO stupid questions.
A red eyed tree frog's colors do vary at night. Temp , humidity, light, mood, interaction with a tank mate, and stress etc can affect their color.
Most of the time mine are a brighter green- even brighter than what you see in these photos. ( they were very stressed when I took these pics) I do not recall a red eyed tree frog of mine having ever been a dark color during the day, however. This would bother me.
I would have to say you should be concerned if your red eyed tree frog stays a dark color during the day ( while it's sleeping) . It's a heads-up !
This would not mean that you frog is doomed.....It happens. But I would, simply, evaluate all the settings , environment within the enclosure (froggie stress,) and the overall health of the frog.
