Is it Ethical to Keep Fish in a Fishbowl or Should Fish Live in a Different Environment?

Pet fish are often overlooked when it comes to proper care and living conditions. Despite the popularity of keeping freshwater fish in households, many owners still choose to keep their fish in small glass bowls, which can be detrimental to their health and well-being.

The standard glass fishbowl lacks filtration, leading to poor water quality with high ammonia levels that can harm the fish. Additionally, these bowls typically hold only one to three gallons of water, which is not sufficient for the fish to thrive. Dr. Benjamin Rosenbloom, a New York „wet vet,“ recommends at least five-gallon tanks for bettas and 40-gallon tanks for goldfish, but this can be challenging in apartment settings. Keeping a fish in a small bowl is equivalent to keeping a human being in a closet, highlighting the inadequate living conditions for these pets.

Fishbowls also often lack plants or other decor that is essential for stimulation. Without proper enrichment, fish can become bored and stressed, leading to health issues such as muscular or orthopedic injuries. The lack of space in fishbowls forces fish to swim in the same endless loop, which can be detrimental to their physical and mental well-being.

Despite the known issues with fishbowls, there is a lack of regulation on their sale. Some retailers have chosen not to sell fishbowls, recognizing the harm they can cause to fish. In 2022, a French aquarium purveyor removed fishbowls from their shelves, citing the negative impact on fish health and well-being. Fish in fishbowls have a significantly shorter lifespan compared to those in properly sized tanks, with some varieties living up to 30 years in ideal conditions.

It is essential to recognize that fish are sentient beings that can feel fear, recognize threats, and even potentially recognize human faces. Research suggests that fish have the capacity to form relationships with their owners and experience emotions. Despite their small size, fish are intelligent creatures that deserve proper care and respect.

In conclusion, it is crucial to provide pet fish with appropriate living conditions that meet their physical and psychological needs. Fish should be housed in adequately sized tanks with proper filtration, enrichment, and care. By understanding and addressing the specific needs of pet fish, we can ensure that they live healthy and fulfilling lives as valued members of our households.
