NERCISU Fish Tank Building Blocks Kit with LED Lights — 830 Pcs STEM Aquarium Set (Shark, Jellyfish, Boat) Ages 8-12+ & Adults

Immerse in an Ocean World You Can Build

Turn a tabletop into a vibrant underwater scene with the NERCISU Fish Tank Building Blocks Set. This 830-piece kit uses durable ABS plastic to craft a lively ecosystem that includes a playful shark, jellyfish, crabs, and colorful coral, all set above a surface scene with a fishing boat. A sunken shipwreck and a treasure chest on the seafloor invite curiosity and discovery, while a glow from the LED lights adds a gentle nighttime ambiance to your display.

What You Build and How It Works

• 830 premium ABS pieces create a detailed ocean landscape, including a shark, jellyfish, crab, fish, coral reefs, a surface boat, a shipwreck, and a treasure chest.
• Gear-operated crab cage on the surface adds motion and interactivity; search for the hidden key to unlock the boat’s lights.
• The treasure chest hides a key that unlocks the fishing boat’s lights, bringing the scene to life with a glow.
• Finished dimensions are about 10.08 x 5.35 x 11.14 inches, making a striking display without real fish.

STEM Learning Through Play

Step-by-step numbered bags, a brick separator, and clear color instructions guide builders through each stage, reducing frustration and encouraging steady progress. The kit supports creativity, problem solving, and fine motor skills, and is well suited for parent-child bonding moments. It also provides an approachable way to talk about marine life and ocean stewardship.

Decorative, Functional, and Grown-Up Friendly

• Display-ready aquarium-style decor that doubles as an engaging teaching tool about marine life and ocean stewardship.
• Compatible with major building-brick brands, so learners can expand the scene with existing collections.
