10 Aquarium Fish for Every Budget


Owning fish can be a very rewarding and relaxing experience. However, to get the most of fish keeping, it’s crucial to have the money to spend to ensure that your aquariums thrive.

By investing in your aquariums, you will ensure that your fish are happy and healthy, and that your aquariums are beautiful to observe.

The Cost of Fish Keeping

The cost of actually keeping fish varies between owners. While some people may only spend $50 on their fish, others easily dish out hundreds or thousands of dollars a year to upgrade and maintain their aquariums. For example, basic supplies include aquariums, substrate, decorations, plants, food, heaters, thermometers, aeration systems, filtration systems, water testing kits, medications, and lighting. However, the more passionate you are with fish keeping, the more money you are likely to spend. For example, some people like to heavily plant their tanks and will spend more money purchasing various plants, fertilizers, and LEDs.

Since it’s difficult to calculate the exact cost for keeping aquarium fish, here is a basic list of 10 suggested fish based on their aquarium size requirements:

1. Bettas

Bettas (betta splendens or Siamese fighting fish) are great for people that have limited space to work with. The highly recommended bare minimum for aquarium size is 2.5 gallons, although 5.5-gallon setups and higher are preferred since they can easily hold cycles. Unfortunately, keeping bettas in the widely available 0.5 to 1-gallon setups is considered by many hobbyists to be cruel since ammonia builds up quickly, the water can’t be consistently heated, and the fish don’t have much space to swim.
