Red eye tree frog discoloration

[vswe711]

Hi Cheri
Thank you for doing this.
To start off with we have one red eye and one green tree frog, together (?? unsure about if thats ok after being on this site)
They all did act fine when we got them and after seeing pictures from when we brought them home and when the whites was dying I should have been able to see the decline, but it was gradual.
First the red eye that is still alive started and still has white spots on his back
Then the the green got brown spots on his back (a little over a week ago we started treating him with ssd cream)
Then the whites got a green algae looking color on his head, and started acting slower, tired, didn't seem to be eating.
The red eye that just died started with the green spotting was treated with the ssd (we thought we should treat everyone because they all had some kind of spotting going on, and we thought that everyone would be susceptible) His health slowly deteriorated, getting skinny and not a good jump.
All of the spotting started about 3 weeks ago, except the red eye that has been about 2 weeks, but he would go back to his normal green at first after the day went on.

1. 2 months
2. green from Petsmart, red eye from Petco
3. I don't know
4.Yes
5. They seemed to be, when their health started declining we weren't sure who was and wasn't eating.
6.Small crickets and mealworms
7.Calcium with D3
8.Up to 85 during the day and it has gotten as low as 68 at night.
9.We try to keep it above 50 on the hygrometer. It is a constant struggle to keep the humidity up, I do mist alot during the day. I finally put plastic wrap on half of the screen top.
11. Spring water and it is changed daily
12. We started with moss then switched to coco fiber
13. UVB 2.0
14. a heater that sticks to the bottom of the tank, didn't seem to keep it warm enough when the Chicagoland temps were in the 40s and 50s, so we added a space heater in the room, for daytime temps.
15. a screen lid and just yesterday I added plastic wrap to half.
