Build. Stack. Create.

Your tank shouldn't look like everyone else's. The KSY Aquatics building-block style mini aquarium lets you stack multiple units vertically or horizontally to create a custom desktop aquascape display. The brick-style studs on top lock into the base of another tank — build a tower of fish rooms, or a connected gallery of planted nano tanks.

Compact, Clear, Conversation-Starter

At roughly 12 × 7.5 × 10.5 cm (4.7 × 3 × 4.1 inches), each tank holds about 0.6 gallons — perfect for a small planted Betta display, a shrimp observation tank, or a desktop snail habitat. The high-clarity acrylic body gives an unobstructed 360° view.

7 Colors to Match Your Setup

Available in White, Blue, Transparent, Yellow, Green, Black, and Red. Each tank is the same size and shape — mix colors for a layered rainbow build, or go all-black for a sleek modern rack.
