Tank-Raised Long-Fin Green Cory Cat (Corydoras aeneus)

Same bronze aeneus-type cory underneath, but bred for trailing, elongated fins that add a bit of drift and movement to what's normally a stocky, workmanlike little catfish. The long-fin trait is purely cosmetic — the foraging habits, the gut-assisted air gulping, the tight shoaling instinct are all identical to a standard-fin aeneus cory.

Care level: Easy · Temperament: Peaceful, shoaling · Max size: ~2.5" · Min tank: 20 gal · Diet: Omnivore, sinking pellets + occasional live/frozen
