Why is It Cruel to Keep a Betta Fish?

Bettas are beautiful fish with bold colors. They’re also known as a jewel or Siamese fighting fish and for good reason. These little guys have some aggressive tendencies that can be both awesome to watch and extremely frustrating. If you’ve ever owned a betta, you know how finicky they can be. One moment they’ll be swimming around like everything is peachy, and the next they’ll start attacking their reflection in the glass of their tank. For some people, this is a deal breaker when it comes to keeping a betta fish as a pet. How can so many people think it’s cruel to keep a betta? It all has to do with what you should expect when owning one of these fish as a pet–and whether or not you have the space (and time) to meet their needs accordingly. Let’s take a closer look at why keeping a betta is cruel if certain conditions aren’t met…

Betta Fish Are Naturally Very Territorial

One of the reasons why many people find betta fish so exciting is that they’re capable of showing aggression towards other fish. This is why they’ve earned the name “fighting fish” because people used to keep them in tiny jars and throw them in ponds to attack other fish. If you have ever seen a betta in action, you know that they can be very territorial. They will bite and fight other fish, especially when they are kept in a small bowl or aquarium. They are often kept in small containers, in which they may feel stressed and threatened. They may attack other fish to defend their territory and generate a feeling of security.

Bettas are very active fish and need a lot of space and light in which to swim and explore. Because they are so active, it is important to make sure that the tank you keep them in is large enough for them to swim around. They should have at least two gallons of water per betta, but larger is better.

You may also want to plant the tank to create a more natural environment. Bettas do prefer to swim in plants, but they cannot be kept with live plants. If you have a betta, be sure to use fake or silk plants. Betta fish are tropical fish and do best in aquariums with warm temperatures between 78 and 82 degrees Fahrenheit. The water should be at least a few degrees warmer, but it should not be warm enough to cause the water to evaporate too quickly.

Bettas Are Sometimes Kept in Tiny Bowls

Some bettas are kept in tiny bowls, which can be extremely cruel. These bowls are usually around two gallons if that. Bettas need to be kept in a large aquarium. They cannot be kept in smaller containers. Bowls are too small for them, and bettas often get sick and die when kept in bowls. Bettas are tropical fish and require warm water. Keeping them in a bowl, therefore, would be both cruel and deadly. Without enough oxygen in the water, the betta is likely to get sick and die because the water will warm up too quickly.
