As there is no way to create an aquarium in Minecraft, it will be up to you to figure it out.
It is best to start simple. Get some glass blocks, some water, and some sand.
This is the simplest and most effective way to create an aquarium. It doesn’t have to be fancy. Just something that can hold fish and other aquatic creatures.
Begin by placing the glass blocks at your preferred height and width. There are many ways to create an aquarium. You can place the blocks however you like or need.
After the glass blocks have been placed, add the sand to the area where they are facing and then water the whole area.
To fill your aquarium full of water, you might have to place blocks from one end to the other.
You should finish the task with something similar to the one shown above. It doesn’t have to be beautiful, but it needs to do the job.
