Share your thoughts: Participate in the risk assessment process for GloFish® Corydoras

Current status: Closed

From March 8, 2025 to April 6, 2025, the New Substances program sought comments, including scientific information and test data that could inform the risk assessment process for the GloFish® Electric Green® Corydoras, GloFish® Moonrise Pink® Corydoras, GloFish® Sunburst Orange® Corydoras as part of the Consultations on certain living organisms new to Canada.

Background

The New Substances program, jointly administered by Environment and Climate Change Canada and Health Canada, is currently evaluating the GloFish® corydoras, notified by Spectrum Brands Canada, on January 23, 2025.

These ornamental fish are domesticated Corydoras anaeus, commonly referred to as “Cory catfish”, that have been genetically engineered to produce unique colours and fluorescence for use in home aquaria. The unmodified Cory catfish has been commercially cultured in the United States since at least 1933. GloFish LLC requested a review by the United States Food and Drug Administration of Orange and Pink Corys in 2021 and Green Corys in 2022. They received decision letters for commercialization in the US market. To develop the lines of fluorescent green, pink, and orange colours using fluorescent proteins, a domesticated albino was used as founder.

All three lines of GloFish® Corydoras have been modified to express different fluorescent proteins that were derived from natural marine organisms such as jellyfish, corals and anemones, giving each GloFish® Corydora their corresponding colour. The Electric Green® Cory contains multiple copies of genetic constructs expressing a green fluorescent protein. The Sunburst Orange® Cory contains multiple copies of a genetic construct expressing an orange fluorescent protein. The Moonrise Pink® Cory contains multiple copies of a genetic construct expressing a red fluorescent protein.

According to the notifier, the safety of these fluorescent proteins has been discussed broadly in the notification, and no cytotoxic or adverse effects have been identified by the notifier. The majority of these fluorescent proteins have been used in GloFish® species for decades, some proteins were in lines which were commercialized as early as 2005, without any reports of adverse effects.

These fish are developed only for ornamental use and are not for human or animal consumption. According to the notifier, their potential to survive in the Canadian environment, including cold winter temperatures is highly unlikely. The genetic modifications are not expected to confer any advantage for surviving in Canadian water bodies.
