Customize the Biome and Environment Inside Your Tank

Generating a Biome

Open the manager menu by right-clicking your tank with an empty hand. From here, you can select and generate a custom biome inside the glass. The mod supports all vanilla biomes plus modded biomes, including cave systems. Choose a biome that matches your creature's natural habitat or your aesthetic preference.

Adjusting Water and Block Scale

Use the manager menu to set the water level inside aquariums, leaving breathing room at the top if desired. You can also change the block scale—this adjusts how large or small the terrain blocks appear, letting you create unique visual effects. A smaller scale makes the environment feel more cramped; a larger scale creates a more expansive look.

Fine-Tuning Your Display

Experiment with different biome and scale combinations to achieve the look you want. A cherry grove with reduced block scale creates an intimate garden feel, while a cave biome at normal scale feels more dramatic and spacious.
