Aquarium Keeper
Look after a living fish tank: drop food, scrub algae, breed happy fish, sell to collectors and decorate with coral, castles and bubbling chests to draw more visitors.
Aquarium Keeper is a calm fish tank simulation with a real economy underneath. Every fish has hunger, health and happiness. Drop pinches of food and watch them chase the flakes, but don't overdo it: leftovers sink, rot and cloud the water. Algae creeps across the glass and fish leave little messes on the sand, so switch to the cleaning tool and rub the tank clear before the water quality bar turns red and your fish get sick.
Happy adult fish of the same species breed, and guppies sometimes have twins. Babies grow into adults that are worth far more, so the core loop is breed, raise and sell. A collector regularly asks for an adult of one species and pays more than double for it. Visitors pay to see a beautiful tank, so every healthy fish and every decoration raises your income. Spend coins on new species, sea plants that slow algae, coral, a castle, a bubble chest that heals fish, a snail that nibbles algae, a filter, a heater, an auto feeder and a bigger tank. Overcrowd it and everyone suffers.
A season lasts ten weeks, about five minutes. Coins earned become aquarium XP that unlocks neon tetras, angelfish, pufferfish and moon jellies for later seasons. Tip: buy a sea plant early and sell extra babies before the tank gets crowded.
How to play
Choose a tool at the bottom. Feed: tap the water to drop food (1 coin per pinch). Clean: tap or rub algae on the glass and mess on the sand to keep the water clear. Sell: tap a fish to sell it; adults are worth more, and the collector pays extra for the species shown at the top. Open the shop to buy fish, decorations and tank upgrades (time pauses while shopping). Visitors pay coins based on how beautiful and happy your tank is. The season ends after week 10; your score is the coins earned.
