Genetically Engineered Pets Hit the Market
psoriac writes "According to this article the Taiwanese Taikong Corporation is starting to sell "Night Pearls" - zebrafish that glow in different red and green patterns thanks to genes from jellyfish and marine coral. US sales are expected to follow."
The Taikong Corporation has info on the fish on their Azoo site. Unfortunately, it appears to only be in Chinese, but you can get the idea from the pictures.
Here are several stories and pictures of the fish.
The pictures (and other sites such as this one) imply that they are "fluorescent" fish, i.e., they glow when bathed in UV light, as opposed to fish that glow without a UV light source.
