Minasoko

Minasoko is a small planted aquarium that lives on its own clock. Begin by choosing one of three tank setups. Stones: cardinal tetras and harlequin rasboras among hairgrass, stem plants, stones and driftwood. Driftwood: anubias on branching wood, with panda corydoras picking up food from the sand below cardinal tetras. Grazers: a film of algae grows on the glass and stones. Otocinclus and snails graze it, leaving visible traces. Tap the feeder on the tank's rim to drop food. Hungry fish swim up to eat. Uneaten food sinks to the sand and gradually breaks down. Your feedings are recorded in the tank's history. Touch a fish to see its health, the water-quality readings and what is affecting it. Press and hold the sand to see the layers beneath that spot and what has happened nearby. Press and hold anywhere else in the tank to read its chronicle. Let go, and you are back in the present. It does not start empty. Every tank begins with sixty days of its own past, so the sand already holds layers and its history already holds events when you first see it. Beneath what you see, the tank's ecosystem is simulated. The fish eat and grow, their waste becomes ammonia, bacteria turn it into nitrite and then nitrate, and the plants take up what they can. Light affects how plants and algae grow. When the balance tips, the water clouds, algae spreads across the glass and stones, and the fish become sluggish, lose color and can die. What dies settles into the sand and breaks down into the water the plants draw on. The tank follows real time. When you come back, it simulates the time that has passed, up to the most recent thirty days; a longer absence is recorded as a pause in the tank's history. Automatic care feeds the fish, tests the water every day, changes water, trims the plants, and shortens the lighting period when the water starts to turn green. In the Grazers tank, automatic care does not scrub the algae. Otocinclus and snails graze it instead. - Three tank setups, each with its own inhabitants, plants and layout - A simulated planted-tank ecosystem: nitrogen cycle, light, algae, plant growth, fish health and death - Every tank begins with sixty days of history - Follows real time, catching up on up to thirty days while you are away - Feed the fish yourself using the feeder, alongside the automatic care - Automatic care - Pinch to zoom, drag or twist to turn the tank, drag with two fingers to pan, double-tap to go back - The tank's text follows your device's language (English or Japanese); the About screen is in English - Works offline.
