Peenuhlope

We have had 2 white's tree frogs for the past almost 2 years. I like them because they are fairly low maintenance and are fun to watch at night. I think they are cute--and i'm not a big animal lover!
  Anyway, we evidently we haven't been taking the best care of them, because one of them seems to be sick. I always guessed that one was male (we named Nico or Nicodemus), and the other a female (we named Peenuhlope), but now I am thinking they are both male. Well, one of them, I think Nico got my attention about a week and a half ago because he was sitting on the water bowl looking at us and awake during the day. They are nocturnal and usually sleep on the highest most hidden walls during the day. Then, at night, he started frantically crawling on the walls back and forth and even hitting the top screen as if he was trying to escape. I noticed his legs and belly looked a little more pink/red than usual so I researched as much as possible online.

 This was our old tank...not ideal for them since it's not very high, and the full screen top didn't keep enough humidity in.
These were taken last friday when we first put him in quarantine:

 These two were taken a few nights ago:

 These two were taken tonight:

   There is a deadly syndrome called red-leg disease that is common to these frogs, caused by the wrong temp/humidity,stress or unsanitary conditions. There was about 5 days between ordering a new water filter that could've exposed him to bacteria. Plus, we are loud and he could've been stressed. IDK. So I isolated him in a 'hospital tank' with clean damp paper towels, a water bowl, a plant for hiding and put it in our room upstairs where it was quiet and warm, He's been there since last friday and hasn't changed. He hasn't eaten the 3 crickets we put in there, and continues with the same behavior. Not lethargic though--very active at night, but not eating. I know this seems ridiculous, since it's such a small animal, not like a dog or something, but I am taking him to a herp vet tomorrow in north richland hills. I feel like it's our responsibility to take care of the pets we have and I don't want him to be in pain, hemorrhaging to death (which is the end result of red leg). Hopefully it's an illness we can treat, or maybe there is some other explanation, i.e. weird mating season behavior or something.

   So we bought a more appropriate cage for them, so they can climb, and are trying to do better with the temps and humidity. The other frog doesn't seem ill, so he is in the new cage while Nico is in the 'hospital' quarantine tank in my room. Here's the new tank:

The other frog seems fairly happy sleeping up high next to this heating pad. He's changed colors a lot since being put in his new home---from green to teal, to brown and now this brownish-green. But its belly still looks white so I don't think he's sick. Which is why the other one is quarantined. :(

 Hope to have good news tomorrow...and not too high of a bill to pay...
