No two bettas alike: 51 painted color sets, patterns and rare fins to discover. Solve the Breeder's Notebook riddles and send a baby to a friend. New in 1.2: one of a kind. Every baby is different now, with 51 color sets taken from hand-painted bettas, butterfly and dragon patterns and rare fins. Solve the riddles in the Breeder's Notebook, earn tank keepsakes by caring for your bettas, discover named breeds, and send a baby to a friend with a short gift code. Your betta also knows you now: it greets you at the glass, follows your finger and jumps for a treat, and bonded pairs lay eggs in a bubble nest. The full Little Tank, with more to look after and more to earn. Twenty-three bettas swim here, including Flame, Red Dragon, Gold, Dumbo, Galaxy, Koi, a special Pixel betta, two females and six AI robot bettas. Each has its own personality. Keep one male in the main tank and give the others a shelter of their own: every shelter holds up to 8 fish (4 of them males) with its own plants and decor, and you can move fish between your tank and any shelter. Put a female in first, add a divider, then the male: as the pair grows fond of each other (watch the affection bar), the divider can come out. Males even blow bubble nests at the surface. Reach level 10 and a pair of Cyber Blue robot bettas arrives as a gift; Steam Gold and Pearl Pink robot pairs are optional one-time purchases. You choose a robot betta's personality yourself. Every feeding, water change and quiet minute with your tank earns experience. Level up and new shelters, backgrounds and plants open as rewards. Swipe sideways through your shelters to pick a favorite. Collect 18 badges along the way. - 23 bettas with their own personalities, including AI robot bettas whose personality you choose - 6 shelters, each with its own fish and decor, and 5 tank backgrounds - Dividers, an affection bar for pairs, and bubble nests - Extra plants for decorating - Levels 1 to 10 with rewards, and 18 badges - Soft music, a quiet heartbeat rhythm, rain, waves, forest and crickets - English, Korean, Chinese and Spanish - No account, no ads, no tracking - Two optional one-time betta pairs (Steam Gold, Pearl Pink); everything else is included

  • This app hasn’t received enough ratings or reviews to display an overview.

One of a kind. • Every baby is different now. 51 color sets taken from hand-painted bettas, from Dawn Peach to Blue Tide, plus butterfly and dragon patterns. • Raise your babies. Fry hatch pale with short fins; their color comes in and their fins grow as they get older. Baby food helps them along. • Rare fins. Combtail, spade tail, over-halfmoon and dumbo ears, plus a few that exist only here. A giant shows up once in a while. • Breeder's Notebook. Each rare fin has a riddle. Work out what the parents and the tank need, and the answer gets written down when you succeed. • Tank keepsakes: almond leaf, blackwater, a heater, a moonstone and more. You earn them by caring for your bettas. They are never sold. • Named breeds to discover, from Cambodian to Skyhawk. • Send a baby to a friend. Share a short gift code; your betta stays with you and your friend gets an egg that takes after it. • A missed day no longer breaks your streak (one rest day a week), and reward eggs wait for you when the basket is full. • The Betta Book now counts only bettas you can meet by playing. • Pearls now buy a bigger egg basket and more room in the shelter. Also new since 1.0: Your betta knows you now. • It comes to the glass to greet you, follows your finger, and jumps for a treat (long-press near the surface). • Eggs! A bonded pair lays eggs in the bubble nest. Hatch them to find rare colors. • Babies can inherit their parents' colors. • Treasure bubbles, daily goals, a treasure chest and pearls. • Betta Book: collect every betta and every color. • Real betta temper: a male flares at a female across the divider, chases her if you remove it too soon, and shows off at a mirror. • Emotion bubbles show how your betta feels. • After level 10, earn Master Stars. • Save and share a card of your betta. Also fixed: affinity, bubble nests and badges are now kept when you reopen the app.
