If there are any ADF experts out there, I'd really appreciate some advice. I've had my frogs for a few years and they've been really healthy, but suddenly, one of my females is floating and can't get to the bottom. When she's under the light, I can see some air making her side bulge. Her skin is healthy and she hasn't eaten anything different. I feed her live bloodworms. Despite the floating, her appetite is fine. Any ideas?
