I am so confused and sad! I purchased a White's Tree Frog yesterday at a reptile expo. He had a small lesion on his hind left leg, but otherwise seemed overall healthy and active. Maybe just slightly underweight, tho. Of course, all yesterday he hid in his new home, and I just left him be. Today, his belly looked very bloated and he was extremely lethargic. He soon died, but not before twitching all over and seeming to be trying to bite. The poor little thing's color is still very bright and pretty, but under his thighs and his feet are very red, like you can see muscle through the skin. I have an ExoTerra 18"x18"x24" tank with a waterfall in the back decor, hydro balls in the bottom with moss covering that. The humidity has stayed right around 50% and the temp in mid 70s. I have a 75w night lamp for temp regulation as my home stays in the very low 60s. I will try and post a pic of the little guy after death, but this is my first time on a forum! If anyone has any insight, I would greatly appreciate it. Sorry for the long winded post!
