Fish bowls are a fun, economical and authentic take on the concept of fishkeeping. But if you’re ready to embark on the fun hobby, it doesn’t require any less attention and maintenance than a bigger version of an aquarium. Constant water changes are a must, because waste products tend to build up quicker if the fish dwells in a small space.

Fish bowl sizes 

Fish bowls come in different shapes and sizes, but the absolute minimum size should be 1 – 2 gallons. However, the bigger a fish’s space is, the happier it will be, so it’s important not to cram it into a tiny space. Having a more spacious living environment is also necessary for the overall happiness of a fish.

Under those circumstances, it will have more freedom, swimming space and a bigger supply of oxygen. As you surely know, a happy fish is a healthy fish. So don’t be stingy when choosing a fish bowl and keep in mind that you can’t go wrong with a little extra space.

Fish bowl types

Fish bowls can be made of glass, plastic, acrylic and even porcelain.

Glass fish bowls
Glass and porcelain are extremely fragile, so you have to be extra careful as to where you decide to place your fish bowl. On the upside, glass is cheap and a commonly used material because it’s durable and cheap.

Acrylic fish bowls
Acrylic is much better when it comes to strength and durability. Despite being lighter, it’s stronger than glass, so where you place your bowl isn’t a problem. Although acrylic has many advantages, in comparison to glass, it’s more expensive and prone to scratches. Over time, it might also turn yellowish.

Plastic fish bowls
Plastic is the least fragile material, but its quality is not as stellar as the other materials we mentioned. It can also look cheap and diminish the overall aesthetic of your fish bowl.

Which fish can I keep in a fish bowl?

There isn’t a vast selection of fish that can thrive in a fish bowl. Every type of fish prefers more space, so if you can choose between a fish bowl and a bigger aquarium, the latter is the best option. But if you specifically want a fish bowl – here are some of the most typical species that will thrive even in such a small environment:

  • Guppies. They are extremely easy to keep and an ideal choice for beginner hobbyists. They don’t require much space in order to live well, making them easy to keep. Owing to their beautiful colors, your fish bowl will look very vibrant!
  • Betta fish. They are often the most popular choice. They love solitude and can survive in small spaces. Still, they love to swim, so a bigger fish bowl is a must.
  • Paradise fish. A relative of the Betta fish, they’re a great alternative if you don’t want a Betta fish. They’re much more tolerant of cold water unlike their cousin fish.
  • Although they’re commonly kept in bowls, Goldfish aren’t an ideal choice for a fish bowl – in captivity, a Goldfish can reach up to 7 inches in size! They also produce a lot of waste, which is a big issue with a tank as small as a fish bowl. The truth is that they’re just extremely hardy. While they’re able to survive in a bowl, they’re most definitely not happy or healthy in one.
  • Schooling fish are also a poor choice – although many Tetras are tiny, they need to be kept in groups, which a small fish bowl can’t support.

Betta fish bowls

If you’re on the lookout for a fish bowl, you’re most likely planning to get a Betta fish. Unlike most fish, this species is fairly undemanding. It’s probably one of the most appropriate species of fish for a bowl because the space they require in order to thrive doesn’t have to be gigantic.

2 gallons of water is the absolute minimum amount suitable for housing a single Betta fish. As long as they have space to swim and a place to hide (which this species enjoys), their needs will be met. But if you’re able to, invest in a bigger fish bowl because every fish likes more space. Your fish shouldn’t just survive, it should enjoy being your pet. If you opt for a male Betta fish, never keep more than one in a bowl because they’re extremely aggressive and will often fight to the death.

When it comes to equipping for a Betta fish, you’ll need:

  • A lid. Because Bettas like to jump, keep a lid over their fish bowl to prevent them from jumping out.
  • A filter. As with every species of fish in any artificial body of water, a filter is a must-have. However, Bettas love stagnant water, so make sure that your filter isn’t creating water movements. For this reason, we recommend getting an undergravel filter, as it’s a stealthy option.
  • A heater. Since this species is tropical, keep track of the water’s temperature at all times by using a thermometer. Bettas can’t live in cold water because it stresses them. The ideal temperature for them is in between 74 and 78 degrees. If the water’s temperature is below this range, a heater will be necessary.
  • Lights. Some fish bowls and aquariums already come with lights, but go easy on the lighting’s settings. Betta fish don’t like strong lights, so choose low-power options.

If you want to decorate your Betta fish bowl, stones and plants are a must because these fish like to have hiding places. Make sure the rocks you put in aren’t sharp because this might lead to fin injuries.

How to clean a fish bowl

On one hand, a fish bowl is a good substitute for a standard aquarium. On the other hand, its small size doesn’t mean that cleaning it is any less important.

As you would with any artificial body of water, perform daily or monthly cleaning tasks. The exterior part of the bowl should always be clean, because you need to have a clear view of what is happening in it at all times. Prevent waste buildup from forming by giving your fish no more than the necessary amount of food. Invest in a quality filter to ensure that the water is always purified. When required, remove the bowl’s gravel and give it a good rinse. Gravel is the main culprit for harboring waste which lowers water quality.

No matter how small your fish bowl is, perform weekly water changes. Ironically enough, such a limited space won’t spare you any upkeep effort, because it’s much easier to make mistakes with a small fish bowl. Because of this, your fish are more prone to change and it’s up to you to create the benefits in such a small living space.

Fish bowl decorations – what to look for

Fish bowls are already small as it is, so a general rule of thumb is not to overdo it with decorations. Choose simple details that don’t take up too much space but still look interesting and are useful for your fish. An important thing to remember is to give them enough space to swim and a few hiding spots to take shelter.

Less is more if you own a fish bowl, because you can incorporate natural-looking decorations instead of plastic ornaments without making it look tacky. At the same time, you’ll want to draw attention solely to your fish.

Try out colorful gravel of different shapes and sizes to figure out which type looks best. The plants you choose also play an important role in the aesthetics of your interior. Thankfully, both living and fake plants are suitable for a fish bowl. But we recommend getting fake plants because they don’t require any upkeep and your fish won’t snack on them.
