* Territoriality: Bettas are naturally territorial, and they see their reflection as an intruder in their space. This instinct is especially strong in males, who fiercely defend their territories during breeding season.
* Agonistic behavior: Bettas display agonistic behavior, which includes aggressive displays and postures to intimidate rivals. They see their reflection as a potential rival and exhibit these behaviors, such as flaring their gills, fins, and even biting the glass.
* Mirror neurons: Some studies suggest that betta fish may have mirror neurons, which allow them to understand that the reflection is a representation of themselves. This may contribute to their heightened aggression, as they perceive the reflection as a direct threat to their dominance.
* Limited visual cues: Bettas have poor depth perception and often mistake their reflection for a real fish, making their aggression more pronounced.
While betta fish may react aggressively towards their reflections, it is important to note that not all individuals will react the same way. Some may be less territorial and show less aggression. However, it is generally advisable to avoid placing mirrors or reflective surfaces near their tanks to minimize the risk of stress and aggression.
Instead of using mirrors, you can create a more stimulating environment for your betta by providing hiding spots, plants, and enriching toys. This will help to redirect their energy and reduce their tendency to become bored and aggressive.
