Every Fish Mutation in Abyss Ranked by Sell Multiplier

This article ranks every fish mutation in the Roblox game Abyss by its sell multiplier, from the most valuable to the least. You’ll find the exact multiplier for each mutation, how the multiplier is applied, and tips for choosing which mutations to keep or sell.

Formula

The sell multiplier for a fish in Abyss is simply the base sell value of the fish multiplied by the mutation’s multiplier. In symbol form:

Sell Price = Base Value × Mutation Multiplier

Where:

• Base Value – the fish’s sell price without any mutation (in coins).
• Mutation Multiplier – the factor applied to the base value, ranging from 0.5× (negative) to 10× (the highest).

Worked Example

Suppose you catch a fish with a base value of 100 coins and it has the Shiny mutation (multiplier 2×). The sell price is:

100 × 2 = 200 coins

If the same fish had the Mythic mutation (multiplier 5×), it would sell for 100 × 5 = 500 coins. The multiplier is applied linearly – no other factors change the result.

Complete Ranked List of Mutations by Sell Multiplier

Below is every mutation currently available in Abyss, ranked from highest to lowest multiplier. Mutations with the same multiplier are grouped together.

1. Mythic – 10×
2. Legendary – 8×
3. Epic – 5×
4. Rare – 3×
5. Shiny – 2×
6. Uncommon – 1.5×
7. Common – 1× (no change)
8. Negative – 0.5× (halves the value)

Note: The Common mutation is essentially the default – it doesn’t change the sell price. Negative is the only mutation that reduces the value.

How the Multiplier Is Applied

The multiplier is applied directly to the fish’s base sell value. This means that a high-tier fish with a high base value will benefit more from a high multiplier than a low-tier fish. For example, a fish with a base value of 1,000 coins and a Mythic mutation sells for 10,000 coins, while a fish with a base value of 100 coins and the same mutation sells for only 1,000 coins.

The mutation is determined at the moment of catching the fish, and it cannot be changed or removed. Once you have the fish, the multiplier is fixed.

How to Choose Which Mutations to Keep

When deciding whether to keep or sell a mutated fish, consider both the multiplier and the base value. A high multiplier on a low-value fish may still be worth less than a low multiplier on a high-value fish. For example:

• A Mythic (10×) on a fish with base value 50 coins = 500 coins.
• A Rare (3×) on a fish with base value 200 coins = 600 coins.

In this case, the Rare fish is worth more despite the lower multiplier. Always check the actual sell price before deciding.

For collection purposes, you may want to keep one of each mutation for display, but for profit, focus on high multipliers and high base values.

Common Mistakes and Misconceptions

One common mistake is assuming that a rarer mutation always means a higher sell price. As shown above, the base value matters just as much. Another misconception is that the Negative mutation has a multiplier of 0 – it actually halves the value, so it’s still sellable, just for less.

Players also sometimes confuse the Shiny mutation with a visual-only effect. In Abyss, Shiny does provide a 2× sell multiplier, so it’s not just cosmetic.

Limits of the Multiplier System

The multiplier system is straightforward, but it has a few limitations. First, the base value of a fish can vary depending on its size and rarity, so two fish of the same species with the same mutation may sell for different amounts. Second, the game may update mutations over time, so this list could change. Finally, the multiplier only affects sell price – it does not affect experience gained or any other gameplay mechanic.

Frequently Asked Questions

What is the highest sell multiplier in Abyss?

The highest sell multiplier is 10×, which comes from the Mythic mutation. This means a fish with a base value of 100 coins would sell for 1,000 coins.

Does the Shiny mutation affect sell price?

Yes, the Shiny mutation provides a 2× sell multiplier. It is not purely cosmetic – it doubles the fish’s sell value.

Can I remove a mutation from a fish?

No, mutations are permanent once a fish is caught. You cannot remove or change a mutation, so you must decide whether to keep or sell the fish as is.

Are there any mutations that lower the sell price?

Yes, the Negative mutation has a 0.5× multiplier, which halves the fish’s sell value. It’s the only mutation that reduces the price.

Do mutations affect anything besides sell price?

No, mutations only affect the sell price. They do not change the fish’s appearance, catch rate, or any other gameplay element.

Is the multiplier applied before or after other bonuses?

The multiplier is applied directly to the base value of the fish. There are no other bonuses that stack with it, so the calculation is always base value × multiplier.
