Molluscarium

Welcome to Molluscarium — your personal mollusc sanctuary built from sun-warmed rocks, rippling waters, and vibrant coral. Discover, care for, and grow over 500 unique mollusc species across nine richly themed aquatic habitats. Build the ultimate mollusc library across nine themed packs — Garden, Tidepool, Freshwater, Coral Reef, Spiral Shells, Bivalves, Hunters, and more. Each species is assigned one of seven rarity tiers — from Common to Ancient. Unlock stunning visual variants: Normal, Painted, Golden, and Rainbow.

From humble garden snails to majestic octopuses, complete your collection one shell at a time. Witness nature's quiet wonder in real time. Eggs hatch into tiny veligers that drift through the water. Watch them grow into magnificent adults — snails crawling on mossy stones, octopuses pulsing through coral, nudibranchs gliding in slow color. Release them for instant rewards, or keep them in your aquarium for steady passive income. Every decision shapes your strategy. Your aquarium keeps flourishing in the background while you work, study, or browse the web.

The automatic feeding system keeps your molluscs happy and fed; when you return, gathered rewards are waiting. No pressure, no timers — just progress at your own pace. Choose from rocks, kelp, coral, decorations, and day-night lighting cycles. Customize multiple habitats exactly the way you want. Build a calm freshwater pond, a sun-dappled tidepool, or a vibrant coral reef — this is your sanctuary, your rules.…
