I have two dwarf aquatic frogs. One of them I have had for 3 months, and the other is a recent addition (2 weeks). Recently their behavior has changed. White ball-looking things have started coming out of the older one's behind, and they both have started digging like crazy into the gravel at the bottom (scooting around and almost twitching). I have looked all over the internet to see if I can find what is going on, and nothing has turned up. I thought at first, the balls were eggs, but after reading, the eggs that I found pictures of look nothing like these balls. These are white, and the eggs are black. I had a frog a while ago where this happened, and the frog ended up passing away! Is this something common, or is this frog going to die too!? ANY suggestions would be greatly appreciated. Thank you for your help!
