Yes, betta fish recognize their owners. Some bettas get excited and swim to the front of the tank when their owners pass by. Bettas mostly associate their owners with food and playtimes, so the more you interact with your betta fish, the more likely they’ll recognize you.
Betta fish can also love their owners. While they don’t have the emotional capacity of a dog or a cat, bettas are still capable of feeling emotions. Over time, betta fish might even form an emotional bond with their owners. You’ll know a betta has bonded with you when it swims faster or becomes interested when you’re near its tank. Sometimes, you might even notice it staring at you or following you around.
