Nearly all fish living in saltwater aquarium tanks began their lives thousands of miles away on warm tropical reefs. These fragile fish and wildlife taken from the reef often die before reaching personal aquariums.


Only 1 in 5 Survive

Most fish taken from the reef die from poisoning, the stress of captivity or inhumane practices used in handling and transport to the pet store. 80% of the fish deaths in personal aquariums are due to poor practices in the supply chain.

Over 40 million Fish Lost

Tropical fish are stewards of the reef. They help keep coral reef ecosystems healthy and in balance. By removing these fish, coral reefs become more susceptible to stress from warming oceans, bleaching, and ocean acidification. Keeping fish on the reef is essential for healthy and resilient coral reef ecosystems.

Cyanide Destroys Reefs

Over 50% of wild-caught aquarium fish purchased from U.S. companies tested positive to exposure to cyanide. Cyanide fishing destroys coral reefs and their wildlife, and over 90% of cyanide-caught fish will die within weeks.

    Help wildlife stay wild! Sign the pledge!

    “I pledge to protect coral reefs and their wildlife by always choosing captive-bred fish for my aquarium, never buying fish captured in the wild, and by urging friends, family, and businesses with saltwater fish tanks to do the same.”
