6 Best Betta Tanks 2020

Poor little betta fish! He has been sitting at the pet store in a teeny, tiny fish bowl without much room to swim.

Thank goodness you saved him and you’ll find him a larger tank to swim in so he can live happily ever after.

There are many good betta rescue stories out there, but not all of them are told by those who actually know how to properly care for a betta.

In our guide below, we’ll help you create the perfect betta tank and provide you with a few tips so that you can ensure a long and happy life for your betta once you’ve taken him home.

How to Choose

There are a few things to take into consideration as you choose the best betta tank for your needs:

  • Number of Fish. While it’s common knowledge that most bettas are better off being the only fish in the tank (especially males since they will combat one another), if the tank is large enough, several female fish can live comfortably together without an issue.

For single fish, you’ll most often see a 1-gallon tank, which is the minimum, but a 2 or 3-gallon tank is even better.

If you’re feeling ambitious and you have the room, you might even opt for a 12-gallon tank (also great if you have a few females sharing a tank). Feeling ambitious and you like a lot of décor? A 20-gallon is the ultima betta mansion!

  • Amount of Décor. One of the fun parts of getting a fish tank is deciding which accessories to use inside.

The most important thing to remember when deciding, however, is not to overcrowd your fish with too many.

Have fun with the décor but make sure you leave your fish plenty of room to swim.

  • Material. Go with glass. Plastic is flimsy and glass is just better overall.

No Bubbles

The first instinct of many new betta owners is to get aeriation bubbles for the tank, seeing as pretty much every other tank they’ve seen requires them.

Betta fish, on the other hand, do not need bubbles. In fact, they are bad for your betta.

Since bettas live in still water in the wild, the bubble can create too much of a current for them and cause them to exert more energy in order to swim against them. This stresses them out, which can lead do disastrous results.

High powered bubbles – no.
Low-powered filtration system – yes.

Top 3 Best Betta Tank Reviews

1. Fluval Spec III Aquarium Kit

This is the most popular choice of betta owners and probably the best betta tank in terms of size and aesthetics.

It comes in white (featured above) or black along with a powerful 31 LED lighting system that will help illuminate the plants and décor below. It also has a three-stage filtration system that will keep the water clean.

Some feel that the water flow is too strong from this filtration system, but custom alterations can be made to reduce it.

At 2.6 gallons (measures 10.8” X 11.8” x 8.7”), this is ideal for a single betta fish.

2. Fluval Edge Aquarium with LED Light

Anyone who has room for a larger tank or who wants multiple bettas will love the Fluval Edge Aquarium.

It’s a step up from the previous Fluval model with a 12-gallon capacity (measures 16.9” X 10.2” X 23.4”) and the same great 3-stage filtration system.

It looks great and it does provide you with plenty of room for your betta(s), but the downside is that it’s difficult to clean. It has a sealed glass top that allows for 3D viewing (and you can fill it to the brim), but when it comes time to clean, you can’t take the top off.

Overall an excellent betta tank, but only if you have the time and patience to deal with the design.

3. Tetra Aquarium Kit

Anyone looking for a fishy palace for their bettas?

A larger tank like this is a serious investment for the serious fish owner. It holds 20 gallons of water and measures 24.2” X 12.4” X 16.7” and it comes in three different color schemes.

The filtration system runs quietly and you get a hood with LED lights on it for your live plants.

You can have a lot of fun decorating a tank like this while still leaving plenty of room for your betta to swim.

It will cost more to maintain since it’s larger, but if you have the room in your home and really want to provide your betta with spacious living quarters or you want a few females, this is a great tank!
