Just 2% of fish species sold for saltwater aquariums can be captive-bred. The ability to identify and choose captive-bred fish for your saltwater aquarium has never been easier. With Tank Watch, the entire list of commercially available, captive-bred saltwater fish is right at your fingertips in the GOOD FISH and GOOD FISH FOR NOVICES lists.

Avoiding fish captured with cyanide is also easier with Tank Watch: just steer clear of the species found in the BAD FISH list which also includes the species captured unsustainably from coral reefs, those not suitable for the average hobbyist, not widely available to consumers, or still in the experimental stages of captive-breeding.


• Up-to-date information at your fingertips for ocean-friendly and conscientious fishkeeping.
• Sort by family, common name(s), or color.
• Quick access lists for "Good Fish", "Bad Fish", "Good Fish for Novices", and "Most Common Bad Fish".

• Includes additional common names, care level rating and more.
• Provides wildlife and ocean-friendly alternatives for conscientious fishkeeping.

I love ❤️ this app because its not the best but I’m making a new fish tank at home and I’m looking for fish and I’ve found 14 fish. So far I’ve just loved it so you have to Download it. Also, it is a good app because you can choose sorting like Good fish,Good fish for novices,Bad fish,Most Common Bad Fish,Idenify by color,Common name,and Family name. This is just an amazing app.🤩🤩

Informative and thought provoking

Great app! Informative and full of detail. Now I understand more of why all of the fish are disappearing from the reefs that I love. More oversight is needed on the methods of the aquarium trade. I would rather see the fish on the reef than dying in tanks and bags waiting to be transported to artificial homes.

Found what I was looking for

Great to have a resource like this for aquarists to make conscious decisions about stocking their tank. Wish they would add more good/bad species as well as coral and live rock guides.
