How Aquariums Work in Fisch?

Personal Aquariums were introduced in Version 1.43.0 (August 2, 2025) as a game-changing feature that allows players to generate passive income while both online and offline. This revolutionary system transforms rare fish from one-time sales into continuous profit generators.

Accessing Your Aquarium

To access the Personal Aquarium feature:

• Reach Level 25 (minimum requirement)
• Find the dark blue “Aquariums” button next to your menu
• Click to open your personal aquarium interface
• Manage your fish collection and profits from this central hub

Core Mechanics

The aquarium system operates on several key mechanics:

Profit Generation: You earn three types of rewards hourly:

• C$ (Coins): 25% of your fish’s current value
• XP: 20% of your fish’s base XP
• Items: Randomized rewards based on fish rarity

• Offline Profits: Even when you’re not playing, your aquarium continues generating profits at 25% of the online rate (excluding items).
• Capacity Limits: Your aquarium can hold a maximum of 8 fish simultaneously, making strategic selection crucial for optimization.

Maximizing Your Aquarium Profits

Optimal Fish Selection

The key to earning millions lies in selecting the right fish for your aquarium. Based on the official formulas and community testing, here are the best choices:

Tier 1: Maximum Profit Fish

• Scylla: The undisputed king of aquarium profits
  • Base value: Extremely high
  • XP generation: 100,000 XP/hour (highest in game)
  • Ideal for both coin and XP farming
• Fragment Fish: Premium item generators
  • Item rate: 10 items/hour (highest possible)
  • Chance for rare rewards: Eclipse Totems, Exalted Relics
  • Perfect for passive rare item farming
• Relic Fish: Balanced profit generators
  • Item rate: 9 items/hour
  • Good coin value with excellent item drop rates
  • Reliable steady income source

Tier 2: Strong Contenders

• Gemstone Fish: 8 items/hour with good value
• Mythic Fish: 6 items/hour with rare drop potential
• Exotic Fish: 7 items/hour with balanced returns

Understanding the Profit Formula

The hourly C$ profit follows a complex but important formula:Line Wrapping Final hourly C$ ≈ (price per kg × current weight × rarity penalty multiplier × fish food multiplier × duplicate penalty × dampened mutation multiplier) ÷ 4

Key Multipliers Explained:

Rarity Penalty Multipliers:

• Apex fish: 0.5× (significant penalty)
• Secret fish: 0.65× (moderate penalty)
• All other rarities: 1× (no penalty)

Mutation Bonuses:

• Shiny mutation: 1.5× multiplier
• Sparkling mutation: 1.5× multiplier
• These stack with other mutation multipliers

Duplicate Penalties:

• First duplicate: -15% profit (0.85×)
• Second duplicate: -28% profit (0.72×)
• Third duplicate: -39% profit (0.61×)
• Formula: approximately 0.8^n where n = number of duplicates

Fish Food Optimization

Fish Food provides essential boosts to maximize your profits. Three types are available:

Fish Food	C$ Boost	XP Boost	Item Boost	Cost	Best For
Guppies’ Best	×1.05	×1.10	×1.0	1,500 C$	XP farming
Fish Chow	×1.15	×1.08	×1.0	4,500 C$	Coin farming
Splash Snacks	×1.06	×1.06	×1.3	25,000 C$	Item farming

Pro Tip: Fish Food regenerates after 1 hour when sold out. Time your purchases strategically to maintain constant boosts.

Advanced Aquarium Strategies In 2025

The Perfect Setup

Based on extensive testing and the official reward tables, here’s the optimal aquarium configuration:

Maximum Item Farming Setup:

• 5× Fragment fish (50 items/hour base)
• 3× Relic fish (27 items/hour base)
• Total: 77 items/hour with Splash Snacks
• Expected rare drops: Multiple Eclipse Totems, Exalted Relics weekly

Maximum Coin Farming Setup:

• 8× Scylla (highest value fish)
• Use Fish Chow for maximum C$ boost
• Avoid duplicates to maintain full profit
• Potential: 1-3 million C$/hour online

Balanced Approach:

• 3× Scylla (coins + XP)
• 3× Fragment fish (items)
• 2× Relic fish (balanced items)
• Use Fish Food based on current needs

Treasure Appraisal Strategy

One of the most powerful techniques mentioned in community guides is Treasure Appraisal:

• Travel to Treasure Island using a Traveler’s Whistle
• Visit the Treasure Appraiser NPC
• Appraise your rare fish before placing them in the aquarium
• Watch values multiply – a 700k fish can become 1.2M+ after appraisal

This single step can nearly double your aquarium profits and is essential for reaching maximum earning potential.

Admin Abuse Event Integration

The most successful aquarium players coordinate their strategy with Admin Abuse events:

• Event Timing: These typically occur every Saturday during updates
• Rare Item Drops: Events shower players with Glitched Caps, Fragment Glitch Shades, and other valuable items
• Strategic Decision: Instead of selling these items immediately, place them in your aquarium for long-term profits
• Compounding Effect: Combine multiple event items for exponential growth

Common Mistakes to Avoid In 2025

1. Overlooking Duplicate Penalties

Many players fill their aquarium with duplicate fish, not realizing the severe profit penalties. Always prioritize variety over quantity.

2. Ignoring Fish Food

Some players neglect Fish Food due to the cost, but the ROI is tremendous. Even Guppies’ Best pays for itself quickly.

3. Selling Rare Items Immediately

The temptation to sell rare items like Fragment Glitch Shades for quick cash is strong, but placing them in aquariums generates far more long-term value.

4. Not Appraising Fish

Skipping the Treasure Appraisal step is like leaving money on the table. Always appraise before aquarium placement.

5. Poor Fish Selection

Using low-value common fish in your aquarium wastes valuable slots. Every slot should contain the highest possible value fish you can obtain.
