RO water is far too clean and pure for keeping fish in. It has no life whatsoever and can not sustain life. It will either need to have other water mixed with it or have the other necessary "chemical and biological impurities" added before it can be used safely. It is used as a "base" by some specialist fish breeders who remake their water to specific parameters in order to be successfull breeding and rearing fish like Discus etc.
A RODI is a Reverse Osmosis De-ionizer used for purifying water, especially in reef tanks.
