Orange-finned Danio

The Orange-finned Danio (Danio kyathit) is a freshwater schooling fish valued for spotted or broken-line body pattern with warm orange fin edging in mature fish. Native to Southeast Asia (Myanmar), this species is popular in planted community aquariums because it combines visual impact with manageable care requirements. A strong choice for aquarists who want movement and pattern variation in one school.

Appearance and Coloration

Orange-finned Danio is known for clean pattern definition and color response that improves under stable water quality, varied feeding, and proper group size. In mature planted aquariums, the body pattern reads clearly even during fast schooling movement.

Size and Lifespan

• Adult size: 3.5 cm (1.4 inches)
• Typical lifespan: 3-5 years with stable parameters and quality diet

Ideal Aquarium Setup

This species performs best in a biologically mature aquarium that prioritizes oxygenation and stable chemistry.

• Tank size: 20 gallons (75 L)
• Temperature: 16-26 C (61-79 F)
• pH: 6.5-7.5
• Aquascape direction: flowing water, open swim zones, and durable planted borders

Behavior and Temperament

Orange-finned Danio is an energetic social species with low aggression when kept in proper numbers. Keep groups of at least 8-10+ individuals so hierarchy and movement are distributed naturally. Good companion options include other active danios, rasboras, and similarly energetic peaceful fish.

Diet and Feeding

Orange-finned Danio is classified here as Omnivore. Build a varied schedule with high-quality staple foods, plus frozen or live options several times per week. A rotating diet supports immunity, activity, and stronger display color.

Breeding Notes

Most cyprinids in this group are egg scatterers. Conditioning with diverse foods and offering fine-leaved plants or spawning media can improve egg survival. If breeding is the goal, move adults after spawning to reduce egg predation.

Why Keep Orange-finned Danio in a Planted Aquarium?

Orange-finned Danio provides movement, contrast, and schooling structure that helps a layout feel alive without overpowering the design. For aquascaping-focused community tanks, it is a practical and visually rewarding choice.
