Building an Aquarium in Minecraft is a pretty easy task. You might need some essential resources to build it, such as:

  • Sand Block from ocean biomes using a shovel.
  • Glass block made with fuel and sand.
  • Spruce trapdoor made out of wood blocks.
  • A bucket to pour water into the tank.
  • Fishes for your aquarium.

These are some of the main components an aquarium demands. Otherwise, you can use different materials for the extra decor in their Minecraft Aquarium.

Key Takeaways

  • Ocean Biomes are an excellent inspiration for any builder to construct anything similar in their house. 
  • The aquarium provides a lively atmosphere and is pretty to look at as a decoration in your house.
  • Building an aquarium requires basic glass blocks, spruce wood, a bucket, and stone. You can also be diverse while choosing the materials for the aquarium.
  • The size of your Minecraft aquarium depends upon the choice of the Aquarium.

Axolotl Aquarium

To build the Axolotl Aquarium:

  • Create the aquarium base using wooden blocks. Make it as big as you want, and add two circular shapes on both walls.
  • Hang some vines on the top to make it more lively, and add glow berries.
  • Complete the third wall slightly different from the other two.
  • Now, join all the sides using spruce plank on the lining and the glass on the inside. Moreover, you can add glass on the floor for a transparent base.
  • I strongly recommend adding shade outside the see-through walls and hanging some vines on the roof. 
  • You can also use blue terracotta and sea lanterns. Now, fill your tank with water using a bucket.

Don’t forget to add seaweed, kelp, sea pickle, and drip leaf to the water because water bodies also have them. Finally, put your Axolotl into the aquarium; now, you have your own Axolotl Aquarium.

Why Did I pick The Axolotl Aquarium?

The Axolotl aquarium has a cylindrical base shape which makes it different and unique from all the other aquariums on this list.

Huge Aquarium

Huge Aquarium

This original and cutting-edge Minecraft aquarium idea is by a well-known gamer named ManDooMiN. Its design is unique and very appealing to the eye. Hence, I recommend you try building this in your world.

For this purpose:

  • You’ll need stripped oak, Quartz bricks, sea lantern, glass, and light blue concrete.
  • In contrast, try out stripped dark oak as a surface of the aquarium.
  • Now make a wall out of 13 Quartz bricks high above the ground.

  • Quartz brick should be used to build three walls.
  • The sea lantern is the final and critical step to making your aquarium glow at night.
  • Create a light blue concrete border around the wall to create the appearance of a blue ocean.
  • Now, cover the rest of the area with glass blocks. Now, fill the aquarium with water using a bucket. Don’t forget to plant seaweeds and kelp.
  • Finally, spawn the tropical fish eggs in your aquarium.

Why Did I Pick The Huge Aquarium?

The Huge aquarium is good for huge bases and makes them look less empty. The whole half-wall design of the aquarium is why I chose it as an aquarium idea.

House In A Fish Tank

Referencing another build by ManDooMiN, this Minecraft Aquarium idea is impressive and ingenious.

  • You will need Adensite, Glass, Stripped Oak Wood, a water bucket, gravel, Stripped spruce wood, and Bone Meal.
  • First, make a frame with an andesite as high as up to 11 blocks.
  • Make a rectangular shape frame and make the gravel floor.
  • Next, make all four walls of spruce wood and stripped oak wood. Leave the space in the middle of all the walls for the glass window.
  • Make a cute little house and add a trapdoor. Install all the essentials of your room.
  • Use a bucket to fill the entire aquarium with water.
  • Add seaweeds using bone meal. You can make a bench with a campfire and spruce door as well.

Why Did I Pick The House in a Fish Tank?

This idea is quite different from all the other aquarium ideas as you as building your base inside a giant aquarium hence, why I chose it. 

Redstone Aquarium

Among the various aquarium ideas in Minecraft, Redstone always stands out for its fascinating outlook. It is from the Mumbo Jumbo.

  • You must start by making a glass room using glass panes. Make a Volcano in the middle of it out of Stone and Cobblestone.
  • Install Redstone in it to make a Redstone clock. (Make sure to keep the Redstone away from the water as it will wash away and mess up your work.)
  • In addition, use a Prismarine slab for stairs and a pop of marine theme.
  • Now, you can add a chest and retract the lid using slime blocks.
  •  Now, add the water to it using a bucket. However, the texture pack used for this aquarium is unsuitable.

Redstone particularly doesn’t go along with water as it washes off the Redstone. So building a Redstone aquarium is quite a fun and daunting task which makes for a good aquarium idea.

Small Aquarium

If you are not a fan of a giant bulky aquarium taking up all the space and resources in your house, then you must try this Small Aquarium Idea. Building this cute aquarium for a lively environment will require less than no time.

  • You will need seagrass, a bucket, sand, a Spruce block, tropical fish, a Spruce trapdoor, and Cyan concrete.  The tank can be as big or small as you want.
  • Start by making a free space in your wall and install one block height of 3 sand blocks. It might look like a cupboard.
  • Now add Spruce plank and spruce trapdoor in the stairs form.
  • Add three glass blocks and fill the space with water using the bucket.
  • Add seaweed and your tropical fish to it. You can also add corals. Now, cover the lid with the spruce plank.

Likewise, you can use the same material to make some of the other small tanks, such as:

The miniature size of this aquarium is what led me to choose this aquarium idea. It’s small and can easily fit inside a small base. You can essentially have multiple of these aquariums around your base.

Wall Cabinet Aquarium

Taffstar has made another aquarium that I found small and easy to make. The exquisite form of the aquarium seems like a wall cabinet. This aquarium is very convenient because it requires less space and can easily fit into a wall. 

  • You must follow the same steps and make space for water inside the wall.
  • Remove all the excess blocks and use oak planks as a base for the aquarium.
  • Cover it with sand and spruce trapdoors.
  • Again, add one block height of the glass and fill the rest of the space with water.
  • Add seagrass and give a bone meal to make it grow. You can also make wooden shelves beside it to make it more useful.
  • Finally, add fish from your resources and have your wall cabinet Aquarium.

The Look of this aquarium is that of a cabinat which makes it look unique and interesting, hence, why I chose it as an aquarium idea.

Modern Aquarium

Here is another aquarium idea I found by VexelVillie.

  • Start by building the floor frame using white concrete. White is perfect for making a difference because this is a modern house.
  • You can make it 11×11 if you want, but it can also be small.
  • Now, use a stripped spruce block to fill the floor frame. Add sea lantern blocks inside the floor for a seamless glow.
  • You can use Minecraft’s best Light Sources described in detail on our website.
  • The next stage is to put glass over the frame, pour water from a bucket, and level it out.
  • Use blue coral blocks to create a pattern on the wall, and add brain corals for vibrant underwater flora.
  • At last, include your turtles or tropical fish. Pour white concrete over the water.

The modern look of this aquarium is what makes this my favorite pick for aquarium ideas. It makes your basic base look modern and up-to-date

Shelf Based Aquarium

If you don’t want to invest a lot of work into making a massive aquarium, a shelf-based little aquarium will suffice. I recommend building these shelves in your in-game house to give it a more modern look.

  • Simple to maintain and construct. It is pretty simple to build an aquarium shelf-based.
  • Only three shelves with a height of one block would be required in the wall.
  • Next, you must cover it with glass and add water to it. Maintain an area of one block, then fill it with lights, corals, seaweed, sea pickles, and fish.
  • Finally, now that the last block is closed, you have your shelves for a tiny aquarium.

Why Did I Pick The Shelf Aquarium?

The shelf aquarium is by far the smallest aquarium built on this list. It can easily be built on any wall or floor (whichever you prefer) or can simply be used as a decor for your base, hence, why I chose it as an aquarium idea.

My Opinion On Aquarium Ideas

I think the Modern Aquarium and the Huge Aquarium ideas are the best aquarium ideas from the list above.

They give your base a more modern and vibrant look and they don’t require much space to build. I essentially built them with starter materials that can be acquired easily.

But I recommend players to try out other aquarium ideas or build your own aquarium based on how you want it to look.
