Just got a white lipped tree frog from a guy on craigslist. I instantly noticed a bulge on its leg and am hoping its just a cyst or a benign tumor. The guy told me its only 8 months old. I got him for $10 so not a bad rehoming fee at all and even if its not going to make it long I wanted to give it a good home. If it is a parasite though I'm not putting it in with my other white lips. BTW I won't be taking it to a vet and paying $80. I was thinking depending on what I learn online after a few weeks if its still there possibly trying to stick it with a needle and see what comes out. Scary thought yes but its just an idea.
The bulge doesn't seem to hinder its movement at all and it feels soft and squishy between the skin and the muscle.
