1) Whimsical Forest Paradise

Jolteon is quite the lucky fish. This awesome Betta tank idea projects the vibe of a fantasy world occupied by nymphs and leprechauns.

Black gravel gives the substrate the look of a forest floor, and a vegetative backdrop and several live plants add a lush feeling to this tank.

Finally, the interesting little huts and rock caves give your Betta fish many places to hide and explore. The natural greenery and many crevices create a Betta paradise and this is a tank that you can be proud to show off.

2) Clear Rocks and Color-Changing LEDs

Give your Betta tank a fun makeover with this colorful tank idea. Color-changing LEDs project a high-class party atmosphere while multi-colored clear rocks at the bottom shimmer in the reflected light.

A few tastefully placed plants give your Betta that hint of natural habitat that he needs. This attractive and flashy tank will give any room a touch of class.

3) Japanese Shrine

This calm and peaceful tank setup mimics the serenity of a Japanese shrine and harkens to the Betta’s Asian origins. Dark gravel substrate gives the impression of a forest floor and larger white rocks add striking contrast.

The light use of plants gives the tank a clean, minimalist look, and the shrine and bridge decorations enhance the Japanese styling.

4) Floating Plant Biotope

This interesting Betta tank is inspired by the rice paddies that the original Betta fish called home. The tank itself is only filled halfway with water, but there is still plenty of room for your fish to swim around and play.

The wide, shallow shape, as well as the small island of floating greenery, creates the environment found in a rice paddy or stream and adds fascinating visual appeal to this setup.

5) Grassy Field

This well-designed tank is both visually striking and pastoral in feeling. The green carpet of live plants that lines the bottom is an intense splash of color and creates a wonderful grassy bed.

The rock decorations jutting out from the center provide bold contrast and the gradual slope of the substrate gives this tank a dynamic feeling.

Pair this with a colorful Betta fish and you’ll have a tank that you won’t want to stop looking at.

6) Tropical Island Living

This tank uses two distinct zones to recreate the feel of a jungle-side beach vacation.

The darker substrate under the jungle section replicates the look of a forest floor, while contrasting light-colored sand forms a relaxing beach. An interesting variety of brightly-colored vegetation creates a unique jungle environment, and the tank light at the top adds a sunny feeling to the whole scene.

Your Betta fish will definitely enjoy his time in this island paradise.

7) Log Cabin

This tank features a hollow log decoration that not only has visual appeal but also gives your Betta a place to lounge and rest.

Purple, green and blue plants add a colorful, natural feel and will make your Betta feel at home. This is a unique tank idea that any Betta will enjoy.

8) Vegetation Variety

Vegetation is the main feature in this beautiful tank.

Bettas love swimming around and exploring soft cover like live plants, and your Betta will love a green environment like this. Even though all the plants are green, this tank features several different kinds of plants for interesting variety.

A dark substrate underneath adds to the jungle feel.

9) Tri-Color Divided Tank

Do you have a divided tank? Then consider adding variety by creating different environments.

This stunning tank uses different color pebbles and plants to make a contrasting visual environment for each section. Tank decorations in three different styles give Bettas a place to explore and add to the impression that we are looking at three different planets side-by-side.

10) Multi-colored Plants

This awesome tank projects neon colors and has an almost alien, futuristic feel.

The multi-colored plants are so bright they are almost luminescent. Black and white pebbles and a grayscale tank decoration contrast heavily with the fluorescent plants and really make the colors pop.

No matter if your Betta is dull or flashy, the contrasts in this tank will make him look right at home.

11) Buddha Ruins

This tank projects the peacefulness of the Buddha and the eeriness of ancient ruins like Angkor Wat.

A Buddha head decoration seems to grow out of the plants surrounding it and provides an interesting focal point. A thicket of vegetation adds to the scene and provides your Betta with many hiding places.

The best part about this tank design is that you can let your plants get overgrown a bit and they’ll make the scene even better. Any Betta will love a peaceful sanctuary like this.

12) Gothic Graveyard

For the darker personalities among us, this tank brings to mind a supernatural gothic graveyard.

Translucent animal decorations and white rocks form headstones arising out of the contrasting black substrate. An ornate gate and a human skull decoration enhance the graveyard atmosphere.

A live plant and a rock add a splash of color and help create a natural environment for your Betta fish.

13) Colorful Jungle

This scene uses color in a very striking manner and brings to mind a jungle settlement, a video game or even the Flintstones.

The brightly colored pebbles and the multi-color plants play off of each other and brighten the scene, while a pineapple hut decoration adds a touch of fun and gives your Betta somewhere to hide. This tank is sure to liven up any room.

14) Planter Pot Paradise

Planter pots are one of the easiest and cheapest ways to add great-looking decorations to your Betta tank. For just a few cents each, planter pots add interesting forms to your tank’s landscape and give your Betta places to hide and explore.

Include a forest of live plants and this tank will make your Betta feel right at home.

15) Bamboo Buddha Forest

This serene tank creatively uses pieces of bamboo with live plants at the top to create the effect of an underwater bamboo forest.

A meditating Buddha tank decoration right in the center draws the eye and adds to the sense of symmetry. Light-colored gravel brightens the tank and a few more live plants create a more natural environment. Your Betta is sure to feel peaceful in a tank like this.

This just may be the most creative tank of the bunch. This tank uses painted lego bricks and PVC piping to recreate a scene from the iconic Super Mario Brothers video game.

While it’s definitely more complex to set up than most other tanks, this would be a fun DIY project and a great conversation piece.

You can even take the concept of creating scenes out of painted lego bricks and design a tank around something completely different.

What do Bettas like in their tank?

There are a few must-haves for your Bettas tank;

  1. Warm water
  2. Filter
  3. Live plants
  4. Caves and hiding places

There are many other things that your Betta will enjoy having in their tank, but those are the must-haves, in my opinion.

What should you not put in a betta fish tank?

There are lots of things you shouldn’t put in your Bettas tank, but here are a few you need to avoid.

  1. Anything with sharp edges. Plastic plants, rocks, and ornaments can sometimes have edges that will tear your Bettas fins.
  2. Fish that are brightly colored and have long flowing fins.
  3. More than one male Betta.

What size tank should you get for a betta fish?

The best size tank for a Betta fish would be at least 10 gallons in size. However, it is not uncommon to find perfectly healthy Betta fish in a 5 gallon tank. That said, I would avoid anything smaller than 5 gallons.

One major element of an attractive Betta fish tank is the use of live plants. This helpful infographic shows you how to create an awesome “carpet” effect with your tank plantings:
