Moonrise Pink GLO Tetra (Gymnocorymbus ternetzi)

This tetra carries the same inserted fluorescent-protein gene as every other GloFish, tech that started life helping researchers watch zebrafish react to waterborne pollutants before it became one of the first genetically modified pets sold in the US. Here it's tuned to a soft glowing pink rather than the more electric primary tones most GloFish lines run. Genuinely heritable color, not a dye, and every bit as easy as a standard tetra.

Care level: Easy · Temperament: Peaceful, shoaling · Max size: ~1.5" · Min tank: 15 gal · Diet: Omnivore, flake/micro-pellet
