Variety of Halfmoon Betta · GloFish

📍 Captive-bred (hybrid)

GloFish Bettas are fluorescent variants of Betta splendens, engineered to display glowing colors under blue LED or blacklight. They share all the same care requirements and temperament as traditional bettas — solitary, labyrinth fish that require warm water and cannot be housed with other male bettas. Males will flare and fight if placed together.

Care Guide

Diet

GloFish Bettas are carnivorous and require high-protein foods including quality betta pellets, frozen bloodworms, and frozen brine shrimp. Feed small portions once daily, only what they can consume in 2-3 minutes, as they are prone to overfeeding and bloating.

Behavior

GloFish Bettas are highly aggressive, solitary fish that must be housed individually—males will fight to the death if placed together. They are labyrinth breathers that surface regularly for air and display elaborate flaring and fin displays, especially under blue LED lighting that enhances their fluorescent coloration.

Breeding

Breeding GloFish Bettas in captivity is difficult and rarely attempted by hobbyists due to their aggressive nature and the complexity of conditioning pairs. Successful breeding requires separate conditioning tanks, careful introduction, and immediate separation after spawning to prevent the male from attacking the female.
