Minecraft aquarium designs worth checking out and building in 2025

Simple and small aquarium

This is a small and simple Minecraft aquarium design built by a Redditor named vexelville.

The player started by making a small hole in the wall where he placed six blue glazed terracotta blocks as a background for the aquarium. Later, they filled the rest of the area with blue concrete blocks. To light up the aquarium, the player placed three sea lanterns that fit the overall aesthetics of the decor perfectly. Glass blocks were then placed over the sea lanterns to create space for water.

Then, water was poured, and the player also placed a few underwater vegetation before placing the fish and covering the rest of the aquarium with white concrete blocks and dark oak wood blocks.

L-shape aquarium

This is a large L-shaped aquarium made by a Minecraft YouTuber named VexelVille, the same person who built the simple aquarium. The player starts by making a three-block deep hole in both the walls, since it will be an L-shaped aquarium.

The hole was filled first with blue coral blocks. Though these blocks will turn gray due to a lack of water, they will eventually turn blue when water is added to the aquarium. The floor of the aquarium is filled with sand blocks so that underwater vegetation can be placed. Both the floor and ceiling also consist of sea lanterns that light up the aquarium.

Lastly, glass panes are placed, water is filled, and all kinds of fish like cod, salmon, and tropical fish are added to finish the aquarium.

The bed of the aquarium has several players where underwater plants are placed. Instead of using sea lanterns, the player used sea pickles to dimly light up the area.
