Care Guide

Galaxy Nemo Koi Halfmoon Bettas thrive in warm, clean aquariums with gentle filtration and minimal water flow. A planted aquarium with broad-leaf plants, floating plants, driftwood, and hiding places provides an ideal environment while reducing stress and encouraging natural behavior.

Maintain stable water parameters and perform regular water changes to promote vibrant coloration, healthy fins, and long-term health.

When housed in a properly sized aquarium, Galaxy Nemo Koi Halfmoon Bettas can coexist with peaceful tank mates such as:

• Corydoras Catfish
• Otocinclus
• Kuhli Loaches
• Nerite Snails
• Mystery Snails
• Amano Shrimp (larger individuals)
• Peaceful Rasboras and small Tetras (with caution)

Avoid keeping them with other male Bettas, fin-nipping fish, or aggressive species.

Feeding

Feed a high-quality Betta diet consisting of premium floating pellets supplemented with frozen or live foods such as bloodworms, daphnia, mosquito larvae, and brine shrimp. Offer small portions once or twice daily to maintain excellent health and coloration.
