Choosing Your Ideal 55-Gallon Fish Tank

Before finalizing your choice, it’s beneficial to ponder different aspects that will help you select the ideal 55-gallon fish tank that suits your needs. We will cover the following considerations to assist your decision-making process:

  1. Shape considerations
  2. Material choices
  3. Cost implications
  4. Fish capacity

Shape Considerations

In selecting a 55-gallon fish tank, you have multiple shape options to consider. The most common shape is the standard rectangular design, which provides a large surface area for fish to swim and explore. However, you can also find more unique options like hexagons and cubes, which offer a different aesthetic and may fit better in certain spaces. To choose the best shape for your needs, consider the available space in your home and your desired fish species’ behavior patterns.

In addition to the standard rectangular shape, custom-shaped fish tanks are also available. To calculate the volume of a custom-shaped fish tank, you must follow these steps:

  1. Determine the base shape area in square inches.
  2. Multiply the base shape area by the height to calculate the total volume of the tank in cubic inches.
  3. Divide the total volume by 231 to determine the gallon capacity of the tank.

This method can also be used to determine the gallon capacity of a tank when its size is unknown.

Material Choices

In terms of material selection for 55-gallon fish tanks, the two primary options are glass and acrylic. Glass aquariums are more cost-effective and resistant to dents or scratches, providing a better visual experience to show off your fish tank decorations. On the other hand, acrylic tanks are almost four times lighter than glass tanks and can better absorb shock, making them more suitable for larger tanks.

To choose the best material for your fish tank, consider your budget and the tank’s placement in your home. If you prefer a more budget-friendly option with enhanced scratch resistance, a glass aquarium may be the best choice. However, if you prioritize a lightweight and shock-absorbing design, an acrylic tank might be a better fit.

Cost Implications

The price of a 55-gallon fish tank can fluctuate considerably, spanning from cost-effective alternatives to pricier, feature-packed models. For example, you can find a basic 55-gallon glass aquarium for less than $100, while high-end models can cost upwards of $500. In addition to the tank itself, there are also costs associated with add-on features and accessories, such as tank stands, hoods, filters, heaters, and decorations. Prices for these items can range from around $50 to several hundred dollars, depending on the brand and quality.

To choose the best option based on your budget, consider comparing prices from different retailers and online marketplaces. Be sure to factor in the cost of additional accessories and ongoing maintenance expenses, such as fish food, filter replacements, and water treatments, when determining the overall affordability of a 55-gallon fish tank.

Fish Capacity

A 55-gallon fish tank provides sufficient room for various fish species, but it’s important to contemplate the number and varieties of fish that can be comfortably accommodated in an aquarium of this size. When considering small aquarium tank size, medium to small active fish are recommended for 55-gallon tanks, as they can comfortably swim and explore the available space. The capacity of a 55-gallon aquarium depends on the species and size of the fish. This tank size can comfortably house 40 to 50 ember tetras. On average, they usually reach a size of 0.8 inches.

When choosing the best 55-gallon fish tank for your needs, consider the types of fish you want to stock and their specific requirements. Some species require more room to swim, while others need hiding spots or specific water conditions. By understanding the needs of your desired fish population, you can better select a fish tank that meets their requirements and provides a healthy and thriving environment.


In conclusion, choosing the right 55-gallon fish tank for your needs involves considering several factors, such as shape, materials, cost, and fish capacity. We have reviewed the top 5 picks for 55-gallon fish tanks, each with its unique advantages and features. By taking the time to understand your individual requirements and preferences, you can make an informed decision and select a fish tank that will provide a beautiful and thriving home for your aquatic friends.
