African Dwarf Frog has Growth on Knee
I have had my african dwarf frog, Fred, for about 2 years now. He has always been healthy and has a great appetite. About 2 months ago he started growing a lump or tumor on his knee joint. It's growing really slowly so I didn't notice it for a while. It's made his knee joint double in size now. I was wondering what this could be and if it needs to be treated? Any info would be great. I'm just worried about the little guy. Thanks!
