Farm a Fish

Farm a Fish (also known as Fishies) is a fishing tycoon and idle simulator on Roblox by Tetra Games, a verified developer group. Launched in July 2025, it has accumulated 21M+ visits with 2,000-8,000 concurrent players and a 96.6% approval rating - one of the highest in the genre.

Players cast bait into pond slots, catch fish across 1,000+ variations, apply weather-triggered mutations that multiply fish value by up to 100x, hatch pets from eggs, and sell everything to fund a growing fish farming empire. The game supports fully offline play through its auto-feeder system, which keeps fish fed and growing while you are logged out:

• 💎 29 weather mutation types transform caught fish value by 2x to 100x - Meteor and Disco Magma are the rarest and most valuable
• 🐾 70+ pets hatched from eggs each grant passive bonuses to fishing speed, sell value, auto-feeding, or bait quality
• 🏠 Craft gear from gathered materials to upgrade pond capacity, bait quality, and sell bonuses
• 💰 Auto-feeders enable passive offline earnings so you can log back in to a full pond ready to sell
• 🗺️ A dedicated Trading Plaza sub-place hosts a player-driven economy for fish, pets, and crafted items

Coins are the primary currency, earned by selling fish and spent on pond expansion, gear crafting, and egg hatches. The tycoon loop centers on scaling up pond slots and optimizing auto-feeders for maximum offline income. Tetra Games partners with content creators to release collaboration-exclusive pond skins and pets not obtainable through normal play.

Farm a Fish competes in the fishing simulator genre alongside Fisch and Fish It, but differentiates with its tycoon expansion layer, deep mutation system, and offline-first design.
