I know a lot about animals, I'm like a little Crocodile Hunter Jr. I've captured and kept all sorts of wild creatures from a very young age. That said, frogs are the creatures I know the least about, so my advice may not be helpful.

Anyway, I think it's probably the same for lots of different animals. One flash, they go, ok that's fine, 5 flashes and they go oh geez that's plenty, 15 flashes they start punching paparazzi and flinging curse words, 50 flashes, full on King Kong mode, break the shackles and ramapage through New York.

That advice is based not on frog knowledge but animal knowledge in general. I find most animals will tolerate a small amount of almost anything, but they all have a breaking point where they become stressed. Good luck and would love to see some pictures!
