Behavioral Tracking for Betta Fish
Betta splendens
ConductVision delivers automated tracking of betta fish aggression, boldness, and lateralization. Quantify mirror-elicited displays, exploration behavior, and turning bias in Betta splendens.
Why Betta Fish in Behavioral Research
The Siamese fighting fish (Betta splendens) is a classic model for studying aggression, individual differences in behavior, and lateralization. Their elaborate mirror-elicited aggressive displays — including opercular flaring, lateral displays, and approach behavior — provide robust, easily quantifiable behavioral endpoints. Boldness/exploration paradigms reveal consistent personality traits across contexts, making bettas ideal for behavioral syndrome research.

What We Measure in Betta Fish
Validated assays with quantitative parameter tracking for Betta splendens.
Mirror tests elicit robust aggressive displays without risk of injury. Opercular flaring, lateral displays, and approach latency provide reliable, repeatable measures of aggression intensity and individual differences.
| Parameter | Unit | Description |
|---|---|---|
| Opercular flaring duration | s | Gill cover display |
| Lateral display frequency | count | Broadside threat posture |
| Approach latency to mirror | s | Aggression onset |
| Total display time | s | Cumulative aggressive behavior |

Boldness assays measure willingness to explore unfamiliar environments. Emergence latency from shelter, total distance traveled, and area covered reveal consistent personality traits that correlate with aggression across contexts.
| Parameter | Unit | Description |
|---|---|---|
| Latency to emerge | s | Time to leave shelter |
| Total distance | mm | Exploration extent |
| Area covered | mm² | Spatial exploration |

Betta fish show consistent lateralized turning preferences in T-maze and Y-maze paradigms, reflecting brain hemispheric specialization. Laterality indices quantify the strength and direction of behavioral asymmetry.
| Parameter | Unit | Description |
|---|---|---|
| Turning bias | % | Left vs right eye preference |
| Laterality index | -1 to +1 | Strength and direction of bias |
