Sick red-eyed tree frog

[douggottschlich]

Hi,

I have 3 young red-eyed tree frogs (captive bred, less than 1 yr, ~ 1.5" long). One has gotten very skinny.Also, his insides seem to be turning to liquid? When he sits on the glass or leaf vertically, his rear looks like a small water balloon, swollen and soft as if filled with liquid.

The other two frogs look fine. Ive had them for about 6 months. They are in a planted terrarium kept at about 70 °F and 90% humidity. Fed on crickets, with weekly calcium dusting.

Anybody have any suggestions?

Thanks,
Doug
