Within the past week or so, my tadpoles/froglets have been developing a strange condition. Their limbs have become extremely swollen, to the point that some of them can barely move around. I'm not sure what is causing the swelling. Their bodies are fine, but their legs and arms look like the michelin man. Any ideas on what could cause this?
In the photo below, you can see a normally developing froglet, and next to it is the swollen one.
