Mango’s Fisharium

Mango’s Fisharium is a slow-paced aquatic sim with a peculiar twist. You play as Mango, a semi-sentient goldfish with a mysterious past and a talent for manipulating tank environments. Your goal is to grow your ecosystem, unlock exotic fish species, and uncover buried secrets in a game that balances zen progression with subtle storytelling.

Swim, Rearrange, Discover

In this game, each fish tank is a level with its own biome. You must feed fish, clean debris, adjust pH levels, and introduce compatible species to unlock synergy bonuses. But Mango isn’t just a caretaker—he manipulates gravity, opens hidden compartments, and collects memory shards floating in strange jelly-like forms. The environment responds to both direct control and timed interactions.

• Species Synergy: Combine fish with matching behaviors to boost tank stats.
• Tank Evolution: As balance is achieved, new areas open up—like reef caves and sunken relics.
• Mango’s Abilities: Unlock gravity flips, object possession, and dream-swim states.

Memory Shards and Background Story

Hidden in the sand and coral are memory fragments—interactive puzzles that offer snippets of Mango’s past. These evolve the narrative from lighthearted management to eerie introspection. Collecting them unlocks new dialogue, tank reactions, and hidden fish with surreal behaviors, including those that whisper riddles or freeze time when observed.

Challenges, Growth Paths, and Secrets

Players can pursue various goals—maximizing fish happiness, unlocking exotic breeds, or progressing through the mystery arc. There’s also a randomized challenge mode where tanks start chaotic and require fast reactions. As you progress, you unlock strange filters that warp time, color, and even control schemes, giving the Fisharium an otherworldly vibe.

• Mutation Tanks: Rare scenarios introduce fish that evolve across sessions.
• Happiness Engine: Manage happiness across species to keep the ecosystem stable.
• Deep Mode: A hidden mechanic that reshapes tanks into surreal environments with narrative consequences.

Mango’s Fisharium is a strange, beautiful, and surprisingly emotional journey beneath the water’s surface. What begins as tank decoration slowly becomes a discovery of memory, loss, and adaptation—told entirely through movement, mood, and mystery.
