FishPond

Build a living pond where every fish has a unique genetic code. Breed for rare traits, balance oxygen and hunger, unlock new species, and watch your ecosystem compose its own soundtrack in real time. Part sim, part idle game, part science experiment gone beautifully wrong.

Every fish in your pond is born with a 12-trait genome — speed, size, hunger, fertility, color, and more — all inherited from its parents and twisted by mutation. Two fast parents might produce something faster. Or something weird. That's the fun part.

Grow a real ecosystem, not a screensaver. Stock your pond with six species, each with its own personality. Minnows school in nervous swarms. Bass lurk near structures and ambush anything that swims too close. Crawfish scuttle along the bottom eating whatever died. Every fish makes its own decisions — hunting, fleeing, mating, resting — based on what's actually happening around it.

Breed with purpose (or reckless curiosity). Use the Genetic Splicer and Sampler to cross-breed fish and chase down rare genetic variants, from "Quickfin" speedsters to the elusive "Perfect Specimen." Save your best genetics to a library, clone them, splice them, and push your lineages further. Over 50 named variants are waiting to be discovered in the Trophy Room.

Keep the balance or watch it collapse. Oxygen is finite. Hunger is relentless. Overpopulate and your pond suffocates. Neglect your scavengers and carcasses pile up. The Harmony system tracks everything — diversity, stability, starvation, extinction — and gates your progression behind it. A thriving pond earns more money, unlocks new species, and opens up powerful tools. A dying one spirals fast.

Your pond writes its own music. A built-in 32-bit audio engine generates the entire soundtrack in real time. Each species contributes its own instruments — minnows bring shimmering bell chimes, bass lay down deep predatory lines, salmon add flowing pads. As populations grow, the tempo climbs. Switch between orchestral, funk, and electronic modes and listen to your ecosystem play itself.

Automate, optimize, expand. Hire fishermen with configurable targeting logic to harvest your pond automatically. Upgrade your auto-feeders, expand your pond to 7x its starting size, and run experiments that reward both stability and controlled chaos — yes, there's a mission for causing an extinction on purpose.
