Do oscar fish recognize their owners?

Yes, oscar fish recognize their owners. Oscar fish are known as water dogs, mainly due to how they resemble puppies as juveniles, but also because they are very intelligent and affectionate like dogs. You’ll know your oscar fish recognize you as their owner when they swim faster when you’re nearby.

Aside from recognizing their owners, oscars can also form an emotional bond with you. Oscars mostly associate their owners with food, so to bond with your oscars, try calling their names and interact with them during meal times.

Additionally, you can put your hand in their tank to interact with them. Just make sure your hands are clean and do not have any soap residues. Also, don’t touch them, as doing so may damage their protective membrane.
