Complete Fish Value, Weight, Mutation & Aquarium Calculator for Roblox Fisch 2026
Welcome to the most comprehensive Fisch Fish Stats & Aquarium Calculator for Roblox Fisch in 2026. This advanced tool helps you calculate fish values, aquarium earnings, mutation bonuses, and catch probabilities with pinpoint accuracy. Whether you're a beginner fisher or a seasoned pro grinding for Mythical catches, our calculator provides instant, accurate results for all your Fisch gaming needs.
The Fisch Fish Calculator is a comprehensive calculation tool designed specifically for Roblox Fisch players. It combines four powerful calculators in one interface:
Understanding how Fisch fish values are calculated is crucial for maximizing your in-game earnings. Every fish in Fisch has a base value that gets modified by several multipliers:
Each fish species has a fixed base value determined by its rarity tier. For example:
The fish weight directly impacts its selling price. Heavier fish can earn up to 2x the base value. The weight multiplier formula is:
Weight is randomly generated when you catch a fish, but using specific rods with high luck can increase your chances of catching heavier specimens.
Mutations are the most significant value multipliers in Fisch. They can increase a fish's value from 1.2x up to an incredible 10x! Top mutations include:
The Personal Aquarium in Fisch is one of the best passive income systems in the game. Our Fisch Aquarium Calculator helps you optimize your aquarium for maximum hourly earnings.
Aquarium income is calculated using this formula:
Hourly Credits = (Total Fish Value × 0.25) × Duplicate Penalty × Food Bonus
Key factors affecting aquarium earnings:
To maximize your aquarium value, follow these strategies:
Mutations are special modifiers that appear on fish, dramatically increasing their sell value. Understanding Fisch mutations is essential for serious players.
Several methods boost your chances of catching mutated fish:
The Fisch catch chance calculator helps you understand the probability mechanics behind catching specific fish rarities.
Fisch uses a weighted probability system where each fish has a base catch chance percentage. The total probability in any location equals 100%, distributed among all available fish.
According to Fischipedia research, 100% rod luck is optimal for catching Legendary and Mythical fish. Higher luck percentages (200%+) actually average out catch chances, making it harder to specifically target rare species. This is why Voyager Rod (85% luck) and Mythical Rod (100% luck) are preferred for grinding Mythical fish.
Understanding Fisch trading values helps you make fair trades and avoid scams:
When evaluating trades, use this formula:
Trade Value = (Base Value × Weight Multiplier × Mutation Multiplier × Attribute Multiplier)
Both sides of the trade should have approximately equal total values (within 10-15%) for fairness.

Tryhard mutation (10x) is currently the best mutation, obtainable with 100% chance using the Tryhard Rod. A Tryhard Megalodon is worth 750,000 C$, making it the most valuable non-event fish in the game.
Aquarium income is 25% of total fish value per hour, modified by duplicate penalties and food bonuses. Use our Aquarium Calculator to input your fish and get instant hourly/daily/weekly projections.
For catching Mythical and Legendary fish, 100% rod luck is optimal. Higher percentages (200%+) actually reduce effectiveness by averaging out all fish chances equally. Voyager Rod (85%) and Mythical Rod (100%) are best for rare fish grinding.
No, a fish can only have one mutation at a time. However, mutations stack with size attributes (Big, Giant, Shiny, Sparkling). Appraising a mutated fish will remove the old mutation if a new one applies.
Fish weight provides a multiplier from 1x (minimum) to 2x (maximum) of the base value. Heavier fish are significantly more valuable. Weight is random but influenced by rod quality and luck.
Each duplicate fish of the same species in your aquarium reduces total value by 10% per duplicate. Having 3 Megalodon instead of 3 different Mythicals can reduce income by 20-30%.
Absolutely! Premium fish food (1.25x) and Deluxe food (1.5x) provide 25-50% income boosts for minimal cost. A 10 million C$ aquarium gains 625,000-1,250,000 C$ extra per hour with food bonuses.
