What’s the best fish tank for Betta?

Betta are extremely popular for their exquisite personalities including their aesthetic coloration, peculiar fins, and their small body shape which makes them suitable for a nano tank.

This astonishing fish has become a household name in the aquatic world and has become a prized possession for the fish keepers and aquarium enthusiasts.

Therefore, they deserve a decent and comfortable home to raise them in, else you may expose them to an unsuitable environment and probably end up losing your prized possession.

They require one of the best tanks for Betta that meets their needs and provides them an environment that mimics their natural habitat.

Therefore in choosing the ideal aquarium for your Betta, the following should be considered in order to provide them with the best possible home they deserve.

Best tank size for Betta

In the wild, Betta is always found occupying shallow streams and rice paddies. Owing to this fact alongside their small body shape many hobbyists suggest they can thrive in small bowls and tanks, but this is not true.

Your Betta should be suitably housed in let’s say a minimum 5 gallon tank. However, to provide them with the necessary accessories to keep them healthy and safe, mimic their natural home and provide them with comfort then a bigger tank should be sought for.

Best filtration for Betta

It is no doubt that Betta are always found in still environments, however they would require a filtered tank to provide them a comfortable and clean home.

As Bettas do not thrive in strong currents, a tank with gentle or adjustable filters should be sought for. In the absence of a tank with a filter, then a separate filter should be provided.

Best LED lighting for Betta

Bettas are displaying exquisite beauty that could make your day at the sight of them even after having a long difficult day. Therefore your tank needs to be lighted so you can always get the best image of your Betta.

A bright LED lighting will be most suitable. This is because they are energy efficient and will really display the exquisite beauty of the Betta to your delight.

A tank with day and moonlighting is perfect to give you the best view and also provide a comfortable environment for your treasured Betta.

Best tank style for Betta

It is obvious that Betta is stylish, therefore their tank should be befitting for their majestic nature. The tank should be void of many obstructing viewing positions that will impede watching the stunning display of your Betta.

This article covers a review of different affordable and easily accessible Betta fish tanks to suit your aquatic lifestyle and provide your Betta with the best aquarium home.
