I've got 2 redeyed treefrogs that I've had for about 6 months. Since yesterday, when they looked fine, one has turned very dark, almost black and seems to have lost considerable volume from its body. The other one is still green and plump but both look like someone drizzled white glue on their backs and the darker one looks just plain bad. They're rarely active during the day and he's been moving around looking uncomfortable.
They're in a planted tank with peat moss for the bottom and a couple of live plants and a water bowl. Temps run from 78 to maybe 82, the room is temp controlled. I fed them both on Sunday during the day so I did't see either of them eat, but the crickets were gone Monday.
I've isolated the dark one for now. No pics as yet, my phone is old and no longer takes them and I'm at work until late. Probably tomorrow before I get the chance to take any.
