Submerged Ruins Aquarium Decor Set – 3D Printed Lost City (10 Gallon Ready)

Turn your aquarium into a cinematic underwater world.

This custom 3D printed “submerged ruins” set creates the look of a long-lost city reclaimed by nature. Designed specifically for a 10-gallon tank, the layout gives depth, hiding spots, and a natural flow that fish and shrimp actually use—not just decoration.

Each structure features realistic architectural detail with subtle aging effects and optional moss accents to give it that authentic, overgrown look without overwhelming the tank.

What you get:
• Multi-building ruined city layout (as shown)
• Designed to fit standard 10-gallon aquariums
• Fish-safe material (PLA+)
• Stable bases for easy placement in substrate
• Great for shrimp, bettas, and small community fish

Why this stands out:
• Not mass-produced – custom printed and unique
• Creates a full scene, not just random decorations
• Provides real hiding spots and swim paths
• Perfect centerpiece for a show tank

Important:
• Tank, fish, heater, and filter NOT included
• Rinse before placing in tank
• Moss/plant growth will naturally enhance the look over time
