Moonrise Pink GLO Corydoras (Corydoras paleatus)

GLO fish are the product of a gene borrowed from naturally fluorescent marine organisms — sea anemones and jellyfish, depending on the color — spliced in decades ago for research purposes before the trade spun off an ornamental line. This pink strain runs the trait through a paleatus-type cory, so under the hood it's still the same barbel-foraging, gut-breathing catfish, just with a color that glows visibly under blue or UV light.
