Bubblepost Aquarium

Your goal

A tiny coastal post office has opened six watercolor aquarium exhibits. Catch a common fish, buy its companion with visitor tickets, feed both for free, then choose the exact child shown by each nursery recipe. Parents stay in the tank. Hungry fish stop growing and breeding, but never die or disappear. Every two seconds visitors leave tickets; fed adult fish and three original decorations attract more visitors. The thirty fish, six habitats, decor and postcards use original watercolor artwork and a local synthesized soundtrack. There are no purchases, random rarity rolls, chat or real-world rewards.

Start your first session

Raise five adult fish and place at least one decoration to open an exhibit. Earn one star for opening, two with all three decorations, and three with all decorations and 90 visitors. Six consecutive bests derive 18 collection stars, 30 album fish, six equal-stat cosmetic themes, three earned postcards and a final lobby opening. Practice opens every exhibit and theme with the same care rules but no ranked points or collection rewards. All six exhibits have finite endings; improving a best keeps existing collection progress.

A useful decision to practice

Use touch, mouse or Tab/Enter/Space on the native buttons. Menus, ads, hiding or freezing the page, slow frames and resizing pause the owned aquarium clock; a fresh Resume is required. Leaving a running opening may offer one explicit visitor/nursery bonus capped at four hours; Collect or Decline consumes that preview once. It can be disabled. Saved eggs, growth, hunger, coins and visitors restore from strict legal receipts. Unreadable or changed outer data stays protected until an explicit reset of this game only. Thirteen complete languages, all original art and the music run locally; optional portal accounts, leaderboards and ads need connectivity. Fictional breeding recipes are not real fish-care advice.
