Aquamarine

Dive into Aquamarine, a cozy fishing and aquarium-keeping game where every catch finds a home.

CAST & REEL
Time your cast, track the bite, and reel it in with skill. Every catch is scored for bite reaction, tracking accuracy, and struggle control, with grades from S to D. Land a rare species and you might just get a Shiny surprise.

THREE LIVING BIOMES
Explore Freshwater, Reef, and Deep Sea each with its own cast of fish species across six rarity tiers, from Common to Mythic. Unlock new biomes as you progress.

YOUR OWN AQUARIUM
Watch your catches swim, feed them, keep their tank clean, and bond with them over time using Bond Charms. Every fish has its own personality and behavior.

NURSERY & BREEDING
Pair up fish in the Nursery and hatch new additions for your collection.

SHOP & DAILY QUESTS
Spend Pearls and Coral Gems earned from fishing and selling in the Shop. Complete Daily Quests, keep your login streak alive, and take on the Bonus Challenge for extra rewards.

A relaxing, low-pressure game about the quiet joy of building a tank full of life, one cast at a time.
