Black Hole Fishing Traits Guide

In Black Hole Fishing, each fish has traits that affect its value and upgrades. This page lists traits and their effects so you can optimize your fish for profit.

🎯 What Are Traits?

Traits are characteristics of fish that determine how much money they are worth. Some traits increase value, while others just change appearance. The more valuable the traits, the more money you earn from that fish.

1. How Traits Work

Traits are inherited from parent fish when you use Fish Press or Hatchery.
Traits can be added directly to fish using Trait Injection.
Traits like size, color, pattern, fin size, and glow all affect fish value.

🎯 Traits List & Effects

Here’s a list of the main traits in Black Hole Fishing and how they affect fish value.

1. Size

Effect: Larger fish are worth more money.
Optimization: Use Trait Injection to increase size. Combine large fish using Fish Press.

2. Color

Effect: Some colors are rarer and more valuable.
Optimization: Breed fish with high-value colors using Hatchery.

3. Pattern

Effect: Certain patterns increase value.
Optimization: Use Hatchery to find rare patterns.

4. Fin Size

Optimization: Use Trait Injection to add fin size.

5. Glow

Effect: Glowing fish are much more valuable.
Optimization: Use Trait Injection to make all your fish glow.

FAQ

Do traits stack?
Yes—focus on stacking high-impact traits (often size and glow) before chasing cosmetic-only rolls.

Should I inject traits early?
Injection is powerful but expensive; use it to finish fish that are already close to ideal.

Where is the full trait math?
Value also depends on systems and upgrades; use this list as a baseline and verify in-game with Paint & Compare.
