Fish genetically engineered to glow blue, green, or red under blacklight have been a big hit among aquarium lovers for years. But the fluorescent pet is not restricted to glass displays anymore. The red- and green-glowing versions, more vivid than normal zebrafish even in natural light, have escaped fish farms in southeastern Brazil and are multiplying in creeks in the Atlantic Forest, a new study shows.
Now, they are one of the first to escape and thrive in nature. Early on, environmentalists worried about the possibility, and Glofish sales were banned in some U.S. states such as California and several countries—including Brazil. Unlike Florida, the Brazilian creeks don’t have any local predators for zebrafish, and Magalhães believes they are now thriving. In 2017 he and colleagues began to survey five creeks in three municipalities, finding transgenic zebrafish in all of them. Every 2 months over 1 year, they collected and measured the animals and their eggs and analyzed their stomach content to see what they were eating.
