## What is Aqua Kurashi?

A little aquarium on your iPhone.

Aqua Kurashi lets you watch and care for tropical fish and freshwater shrimp in a small planted tank. Start with three neon tetras and two shrimp. Feed them, change the water, and wipe algae from the front glass. With daily care, your fish grow to adulthood in about a week.

WATCH YOUR TANK
• Enjoy the tank in portrait or landscape. Pinch to look closely at a fish, or pull back to see the whole aquarium.
• The light changes between day and night. At night, the fish rest near the bottom.
• Turn the aquarium light on or off, or hide the controls in viewing mode.
• The tank now sits in a gallery room. Seven pictures above it rotate with the day of the week; tap the picture to switch its light on or off.

CARE FOR YOUR FISH
• Tap the water to feed them. Uneaten food can cloud the water.
• Use a hose to drain about half the water, then refill the tank.
• Wipe algae from the front glass with your finger.

OBSERVE AND DISCOVER
• Choose a fish in Observe mode and the camera follows it as it swims.
• Capture a photo or video of 12 behaviors, including yawning, schooling, and shrimp grazing, to record them as discoveries. Each discovery keeps a short, two-second video in your journal.
• Save photos and videos of up to 30 seconds to your iPhone's Photos app.
• Explore an encyclopedia of the fish, shrimp, and ornaments in your aquarium.

GROW YOUR AQUARIUM
• Keep caring for your tank to unlock guppies, penguin tetras, and black neon tetras. Record seven kinds of discoveries to welcome cardinal tetras.
• Add rummy-nose tetras, angelfish, discus, and a set of three fishing-cat ornaments with one-time in-app purchases.

No account is required, and there are no ads. Your aquarium data is stored on your iPhone. Photo Library access is requested only when you choose to save media, with permission to add photos and videos only.

For iPhone with iOS 17 or later.

## Version history (last 3 releases)

### 1.1.1 — 2026-10-02

■ A new room
The tank now sits in a gallery-like room: a wooden cabinet with a stone top in front of a white wall. By day, dust glitters in the light from the window; at night the room goes dark and only the tank and the picture glow.

■ A different picture every day
A picture as wide as the tank hangs above it. Seven pieces - calligraphy, ink landscapes, fish in ink, a botanical study and more - change with the day of the week. Tap the picture to switch its light on or off.

■ Ornaments in the encyclopedia
The fishing old man and the fishing cats have their own pages.

■ Light colour on a long press
Press and hold the Light button to choose one of five colours.
