Fire belly toads don't move just hide

[Heatheranne]

They may just be adjusting to the vibration and noise from the waterfall. Try adding a land area on the other side with a cave or more plants and see if that makes them happier. A little place to rest and hide. You could try cover the outside side wall of the rank with a background too. That helps them to feel secure.

Thanks I'll try that what do you suggest for land substrates? Also any reasons why I've never heard them make noise?
