Long-Fin Cosmic Blue GLO Tetra (Gymnocorymbus ternetzi)

Same electric-blue fluorescent gene, among the harder colors in the GloFish lineup to express cleanly, bred here onto a long-fin tetra body with trailing dorsal and caudal fins. The extra fin surface slows the swim slightly compared to the standard-fin version, so pair with equally calm tankmates. Genuinely heritable color, holding steady for life.

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