Betta vs. Guppy

Key Differentiation

Guppies are livebearing poeciliids; bettas are anabantoids that build bubble nests and often have longer unpaired fins.

How to Identify Betta from a Photograph

Standard operating procedures for photographers and field naturalists submitting sightings for verification.

1. Critical Photo Angles

📷Clear side profile
📷Head/face close-up
📷Full body in natural light

2. Key Diagnostic Field Marks

🔍Labyrinth air-breathing
🔍Long fins (males)
🔍Upturned mouth

3. Photographic Pitfalls to Avoid

⚠️Confusing with guppies (livebearers with different body/fin plans)
⚠️Sexing by color alone

Camera Lighting Advice: Avoid harsh flash that blows out iridescence.
