Buying Guide for Choosing the Right Nano Aquarium

Guide for Choosing the Right Nano Aquarium

This guide will be featuring the more important and essential factors that you would have to keep in mind when picking out the Nano aquarium for you.

The Size

Be aware that the Nano aquarium has the capacity of holding at least 2.4 gallons or equivalent to 10 gallons. Anything lesser than this capacity is no longer a Nano aquarium but instead is already classified as Pico aquarium. Freshwater Nano aquariums should have a maximum size of about 15 gallons. Saltwater Nano aquariums, on the other hand, requires a much larger capacity of 25 gallons. In choosing, you should consider the aquarium’s base and whether it would be ideal for the room where it will be placed. Larger means heavier, so it would mean that it should have a stable, sturdier base.

Its Shape

The majority of the aquariums come in a rectangular shape. Some fish tanks are higher than being wide, and some may be longer than the other. Keep in mind that you must pick the Nano aquarium, which will fit perfectly on the spot where you wish to place it, whether on your desk or on a table.

Fish Species that would be placed

Consider the factors of whether you have hardier freshwater fishes or whether you are going for a more colorful, vibrant aquatic life form and ocean-dwelling fishes. In terms of the aquatic environment, different fish species would mean different requirements and needs. Generally speaking, most of the time, it is best to stick with freshwater fish species because they are easier to maintain.

Is it glass or acrylic?

If you are going for the feel or look of a miniature aquatic environment or ecosystem, glass aquariums are preferable as they provide more rigidity and are more scratch resistant. Glass aquariums also tend to cost lesser, and distortion is less noticeable. When it comes to acrylic, on the other hand, it has the aesthetically-pleasing style and shape that most want. Acrylic aquariums, too, are lighter than glass ones.

Other Aquarium Features and Components

When it comes to set up, the majority of aquariums require the same basic setups. Additionally, the aquarium needs to have an efficient filtration system for managing wastes and keeping the water clean by getting rid of other impurities. You might also need to consider the appropriate lighting system and having a heater, depending on the fish species you have and your location. What also matters as well when picking out your Nano aquarium are the aquarium decorations, aquatic plant lives, and the fish aquarium substrate.
