I had no idea that ro-di water was bad for amphibians, thankfully I use de-chlorinated tap water for them(seachem prime as my conditioner)

I do know that ro-di(reverse osmosis de-ionized) water does not cause problems with fish, and is actually recommended because the parameters will always be the same. Keeps with more sensitive fish such as discus even have ro-di filters in their homes.
