I think the problem is your diet. Feeding freeze-dried "anything" can harm aquatic frogs. I suggest feeding one of the pellet foods that are available, like Repto-Min. Nightcrawlers are very much appreciated. There are many opinions about what to feed your frogs, I can only share with you how I have fed my clawed frogs. I have 2 pair of frogs that I have had for 20+ years.
