Fish Harmony is meant to give comprehensive compatibility data for every type of aquarium fish. Not sure if a lionfish is compatible with a clownfish (hint: it isn't)? Fish Harmony will also let you know if that kind of fish is Reef Safe, Reef Safe With Caution or Not Reef Safe (in saltwater mode only, obviously!), to prevent your coral from being munched on! You can also use the Compare Fish-To-Fish button to do a 1:1 comparison of your chosen fish to another. For example, let's say you chose "Butterflyfish," and you want to see if it is compatible with Clownfish. You could just browse the "browse view" for Clownfish, but by clicking the "fish-to-fish", you can find the exact fish you are looking to compare with the Butterflyfish. Available for both freshwater and saltwater. Let us know what you think! Leave feedback or a review please! Thanks so much!
