Is hydrogen peroxide safe to use on aquarium fish
1 Answer
Published on May 26th, 2018
Hydrogen peroxide can be used but it has the potential to be somewhat harsh on many species of fish. Unless you need to use it for a specific reason such as to eliminate a particular organism that is susceptible to H2O2, I would shy away from this instead electing to use something designed specifically with aquatic animals in mind. Hope this makes sense.
