It is considered safe for all fish. There are three important things to remember though:
1. It is harmful to crustaceans (shrimp or crabs).
2. If you use it for soft water and/or acid water with low alkalinity, dissolve tablets before adding to aquarium.
3. If you have carbon in your filter, you need to remove that.
