Additionally, tank temperature plays a vital role in betta’s behavior. They surf the tank glass and erratic behavior stop shifting and be lazy for too much hot water or cold water.

That’s why you should maintain the ideal betta’s tank temperature 78 degrees F though their temperature standard is 76 to 85 degrees F.

Both male and female bettas can exhibit glass surfing behavior in the aquarium. Glass surfing is not gender-specific and can occur in response to various environmental factors that may cause stress or discomfort to the fish.

However, it is important to note that male bettas are generally more active and territorial than female bettas, and they may be more prone to glass surfing if they feel threatened or agitated.
