Aquarium · Plinka

Aquarium is an aquarium the child draws. DRAW YOUR OWN FISH In The Fish Workshop you pick species, colour, pattern, body, fins, tail, eyes and temperament. Eight species — fish, eel, pufferfish, flounder, seahorse, betta, angelfish and ray — combine with eight patterns. The fish you draw is exactly the fish that swims. LOOK AFTER THEM Feed pellets, flakes, worms or algae treats — different species want different things. Pet them, tickle them, scrub the glass, decorate with plants, rocks, shells, chests, caves and castles. No fish can get sick, none can die, nothing can be done wrong. THEY GROW UP AND HAVE BABIES Every fish passes through five life stages, from fry to the elder of the pond. Two fish who become friends may leave eggs, and the baby inherits its parents' colour and shape — sometimes in a pattern the workshop cannot make. THE POND KEEPS LIVING Weather drifts on its own, the season follows the real calendar, and night falls when it actually falls. Come back after a few days and something will have happened while you were away. COLLECT AND DISCOVER A discovery book, a treasure shelf and a case of every fish combination fill in as you play. New furniture arrives by itself the more care you give. SHARE Make a card of your favourite fish, or a family photo of the whole school. FOR PARENTS No ads. No tracking. Nothing is collected — the app contains no networking code at all and works entirely offline. No timers, no failure states, no daily quests nagging for attention. Free to start. A single one-time purchase unlocks unlimited fish of your own — no subscriptions. Everything you see is drawn by the app itself and everything you hear is synthesised live. The bubbling of the tank is even tuned to the colours of your fish.
