Use Tank Watch to:

  • Easily identify the fishes most commonly seen in saltwater tanks
  • Learn their origin:
    • Good Fish may be captive-bred*
    • Bad Fish are unsustainably captured in the wild
  • Become a Coral Reef Champion




Why Do Aquariums Harm Reefs and Wildlife?

Nearly all the animals housed in saltwater tanks began their lives on coral reefs thousands of miles away. Consumer demand from saltwater aquarists is responsible for the annual capture and transport of tens of millions of reef fishes and other creatures.

Most of this fragile wildlife quickly succumbs to the stressors of captivity. For each one surviving the journey from reef to tank, up to nine others may have died along the way.

Coral reefs suffer, too. Many are destroyed from cyanide illegally used in the capture of millions of fish. Other reefs lose their resilience from depletion of animal’s key to ecosystem health and balance.

Become a Coral Reef Champion

Fishes bred in captivity typically fare better within the small confines and artificial diets inherent in saltwater fishkeeping. Dozens of captive bred species are now available for saltwater tanks.

Make a difference by pledging to protect wildlife and reefs.

  • Use Tank Watch to identify the captive-bred or good fish, from the wild or bad fish.
  • Discourage the keeping of wildlife in saltwater tanks
  • Urge consumers and businesses to only keep captive bred animals in their tanks; or better yet
  • Switch to a virtual reef display with an UNtanked system , available at

* For a Good Fish rating, captive-bred status of individual animals must be confirmed.
