GloFish® Long-Fin Tetras are a captivating variety of the already popular GloFish® Tetras, which are themselves a genetically modified version of the traditional Black Skirt Tetra, Gymnocorymbus ternetzi. This particular variant combines the stunning fluorescent colors characteristic of GloFish® with the elegant, flowing fins of long-fin varieties, creating an aquarium inhabitant of remarkable beauty and grace. The genetic modification not only imbues these fish with vibrant, neon hues that glow under certain types of aquarium lighting but also enhances their finnage, adding a dramatic flair to their appearance.

The introduction of genes from biofluorescent marine organisms allows GloFish® Long-Fin Tetras to display a range of brilliant colors, such as pink, green, orange, blue, and purple. These colors are permanent and inheritable, meaning they do not fade over time and can be passed down to offspring, although breeding GloFish® for commercial purposes is restricted by patents and copyrights held by the developers.

Caring for GloFish® Long-Fin Tetras involves maintaining an aquarium environment that caters to their needs for clean, stable water conditions and a temperature that mimics their tropical origins. As schooling fish, they exhibit the best behavior and show reduced stress levels when kept in groups. The long fins of this variety make them especially stunning when swimming in schools, although their delicate finnage may require protection from overly aggressive tank mates or sharp aquarium decorations that could cause harm.

Their diet is omnivorous, similar to that of their non-modified counterparts, and should include high-quality flake foods, pellets, and occasional live or frozen treats to ensure a balanced nutrition that supports their health and vitality.

Breeding GloFish® Long-Fin Tetras is similar to breeding standard GloFish® Tetras and their ancestor species, the Black Skirt Tetra. However, enthusiasts should be aware of the legal restrictions on breeding GloFish® due to intellectual property rights. Unauthorized propagation of these genetically modified organisms is prohibited.

In community aquariums, GloFish® Long-Fin Tetras are generally peaceful and can coexist with other similarly sized, non-aggressive species. Care should be taken to avoid pairing them with fin-nippers or larger, more dominant fish that may see their flowing fins as targets.

In summary, GloFish® Long-Fin Tetras offer aquarium enthusiasts a unique and visually striking option for adding color and movement to freshwater tanks. Their care requirements are manageable for aquarists of all experience levels, making them a delightful choice for those looking to enhance the aesthetic appeal of their aquatic setups with these genetically modified wonders of the aquarium world.
