The glofish tetras that we see at pet stores today got their colorful disposition from their parents – the fluorescent protein gene is passed down from generation to generation. Note that only the first generations of glofish tetras were injected with the fluorescent gene. The genes used were extracted from jellyfish and other marine organisms. Fluorescent protein genes were injected into black skirt tetras’ embryos, which led them to have a luminous appearance. However, both varieties were made by genetically modifying black skirt tetras that originally come from Paraguay and Guapore Basins in South America, where they inhabit slow-moving creeks and upper layers of the water.Īnd as you already know, glofish tetras were made by genetically modifying the eggs of regular black skirt tetras. There are two glofish tetras variants – standard and long-finned variants.Ĭredit: Dennis Amith (Creative Commons license) I will cover habitat requirements, water parameters, breeding, tankmates, and so much more. In this one-stop guide, I will tell you all there’s to know about caring for glofish tetras. It makes them an approachable and manageable option for aquarists of all skill levels. Second, they’re literally a piece of cake to take care of. Glofish tetras are among my favorite glofish species for a couple of reasons.įirst, their interesting shape and colors quickly set them apart from other fish in the tank. And ever since their first launch, glofish tetras have steeply risen to popularity and made their way into the homes of million Americans. The same company behind glofish danios, Yorktown Technologies, are their creators. Glofish tetras were launched around 2013.
