## What is AquaKeeper?

Decorate an aquarium with rocks, driftwood and plants, then cycle the water and raise 5 fish species (guppies in 5 color strains, neon tetras, White Cloud Mountain minnows, corydoras and a betta) plus a clean-up crew of cherry and amano shrimp, otocinclus and nerite snails.

Two modes
- Easy mode: focus on decorating. Place rock and plants freely, see water stats on screen, and manage the tank with one-tap actions.
- Fishkeeping simulator: the hobby recreated with hands-on tools. Water quality is hidden, and you learn it by running reagent tests.

What you do
- Pour substrate by the cup and let it settle at a natural angle; sculpt, dig and level it by hand
- Place rock and driftwood. Unsoaked driftwood floats, sinks after a few days, and tints the water
- Fill the tank with a jug. Pour without a plate and you dig craters and cloud the water
- Plant and replant aquatic greens with tweezers. Too shallow and they float, too deep and they rot
- Manage water quality and temperature with filters (sponge, hang-on-back, canister) and a heater
- Run reagent tests for ammonia, nitrite, nitrate and pH while the tank goes through the nitrogen cycle
- Keep and breed 5 guppy color strains, and feed them by hand
- Deal with fishkeeping risks such as ich (white spot disease), low oxygen and overcrowding

Look and feel
A volumetric water shader, LED caustic shadows, and lighting that changes from day to night. On mobile, touch controls and quality presets (LOW to ULTRA) adjust performance to your phone.
