I believe it could have Elfda. I picked up a bottle of the stuff a while ago, incase I ever needed it. (I have various things like that in my frog drawer, you never know.)
So when I picked up my fantasy in April, he was showing bad signs of stress during feeding, throwig his head up and stretching his back legs. So I gave him one, dropped him back in his enclosure after.
The next day it was like he was a completely different animal.
Then a few days later, I was remoddeling a rack here, got a little noisy, stress symptoms again. Did the electrolyte bath again and in the half hour he was in there, his colour changed from dark to bright green and he was doing better again.
So I would recommend it for any frog that shows signs of stress.
