Roblox Dive Down: All Fish Mutations & How to Get Them (June 2026)
In Roblox Dive Down, fish mutations are special variants that dramatically increase your fish’s sell price and passive income generation. Mutations are divided into two categories: Ocean Mutations (Silver, Gold, Rainbow) found randomly while diving, and Weather Mutations (Frozen, Shocked, Chocolate) that trigger on aquarium fish during specific server weather events. Mastering these mutations is the key to building massive wealth in Dive Down.
Quick Reference: All Mutations & Multipliers
| Mutation Type | Multiplier | How to Obtain | Best For |
|---|---|---|---|
| Silver | 2.4x | Random ocean spawn | Early/mid-game profit |
| Gold | 2.7x | Random ocean spawn | High-value selling |
| Rainbow | 3.0x | Rare ocean spawn | Maximum profit |
| Frozen | 1.5x | Snow weather event | Aquarium income |
| Shocked | 1.9x | Storm weather event | Balanced income |
| Chocolate | 2.2x | Chocolate Rain event | Best weather mutation |
Understanding Fish Mutations in Dive Down
Fish mutations are special variants that apply powerful multipliers to both your fish’s passive income (money per second) and sell value. These rare variants are easily identifiable by their unique color schemes and floating name tags. Understanding how each mutation type works is crucial for maximizing your Dive Down economy.

Why Mutations Matter?
Mutations are the ultimate wealth accelerator in Dive Down. While regular fish provide steady income, mutated fish can multiply your earnings by up to 3x their normal value. This makes finding and farming mutated fish essential for:
- Rapid progression through game content
- Affording expensive equipment upgrades
- Completing rebirth requirements faster
- Building massive aquariums with high-value fish
- Competing on leaderboards for top positions
Ocean Mutations: Complete Guide
Ocean mutations are the most valuable mutations in Dive Down, found randomly while diving in any ocean biome. These mutations occur naturally and offer the highest multipliers in the game.
Silver Mutation (2.4x Multiplier)
The Silver mutation is the most common Ocean mutation but still provides excellent value for early and mid-game progression.
How to Identify:
- Completely silver body appearance
- “Silver” text floating above the fish
- Slightly metallic sheen in water
Farming Strategy: Silver mutations can spawn in any ocean area, making them accessible to all players. While they’re the most common Ocean mutation, don’t waste time specifically hunting for them on common fish. Instead, focus on deeper biomes where higher-rarity fish spawn naturally.
Best Targets:
- Epic rarity fish in Coral Reef (30-70m)
- Legendary fish in Twilight Zone (71-165m)
- Mythical fish in Deep Ocean (165-280m)
Gold Mutation (2.7x Multiplier)
Gold mutations offer significantly better multipliers than Silver and are rarer to find.
How to Identify:
- Bright golden yellow body
- “Gold” text floating above the fish
- Highly visible even from a distance
Farming Strategy: Gold mutations have lower spawn rates than Silver but appear in all ocean zones. The key is to spend more time in deeper waters where higher base-value fish spawn. A Gold mutation on a Legendary or Mythical fish can provide massive lump-sum payouts when sold.
Pro Tip: Focus your diving efforts in the Deep Ocean (165-280m) and Deep Dark (281-560m) zones where you’ll find the highest base-value fish that benefit most from the 2.7x multiplier.
Rainbow Mutation (3.0x Multiplier)
The Rainbow mutation is the holy grail of Dive Down mutations, offering the highest multiplier in the game at 3.0x.
How to Identify:
- Constantly shifting rainbow colors (red, yellow, green, pink, blue)
- “Rainbow” text floating above the fish
- Unmistakable visual effect in water
Farming Strategy: Rainbow mutations have the lowest spawn chance of all Ocean mutations, making them extremely rare. Your best strategy is to:
- Dive frequently in the deepest biomes (The Trenches and Atlantis)
- Prioritize high-rarity fish (Mythical, Secret, Divine)
- Use private servers to reduce competition
- Equip optimal gear (heaviest weights, best O2 tanks)
Ultimate Target: A Rainbow Divine Mermaid from Atlantis would be the most valuable single fish in the game, combining the highest base rarity with the maximum mutation multiplier.
Weather Mutations: Complete Guide
Weather mutations work differently from Ocean mutations. Instead of spawning in the ocean, these mutations are applied to fish already inside your aquarium during special weather events. Weather events last approximately 3 minutes and occur randomly on servers.
Understanding Weather Events
Weather events are server-wide phenomena that can trigger mutations on all fish in your aquarium simultaneously. This makes Weather mutations incredibly powerful for scaling passive income across multiple fish at once.
Key Points:
- Weather events last up to 3 minutes
- They affect all fish in your aquarium simultaneously
- You can manually trigger weather using the Weather Machine (costs Robux)
- Weather mutations cannot be obtained by diving
Frozen Mutation (1.5x Multiplier)
Triggered during Snow weather events, the Frozen mutation provides a modest 1.5x multiplier to affected fish.
How to Identify:
- Blue tint on affected fish
- Fish appears trapped inside an ice cube
- “Frozen” label appears in aquarium menu
Strategy: While Frozen has the lowest Weather multiplier, it’s still valuable for boosting passive income. Before a Snow event, fill your aquarium with your highest base-value fish to maximize the 1.5x boost across multiple specimens.
Shocked Mutation (1.9x Multiplier)
The Shocked mutation activates during Storm weather events, providing a solid 1.9x multiplier.
How to Identify:
- Pink electrical aura around affected fish
- “Shocked” label appears in aquarium menu
- Glowing effect visible in aquarium
Strategy: Storm events offer better multipliers than Snow, making them more valuable for income generation. Keep an eye on weather announcements and prepare your aquarium with your best catches before Storm events trigger.
Chocolate Mutation (2.2x Multiplier)
The Chocolate mutation is currently the best Weather mutation, offering a 2.2x multiplier during Chocolate Rain events.
How to Identify:
- Dark brown coloration on affected fish
- “Chocolate” label appears in aquarium menu
- Distinctive chocolate appearance
Strategy: Chocolate Rain events provide the highest Weather mutation multiplier, making them extremely valuable for passive income scaling. Consider manually triggering Chocolate Rain using the Weather Machine if you’re focused on building long-term aquarium income.
Advanced Mutation Strategies
The Sell vs. Keep Strategy
Understanding when to sell mutated fish versus keeping them in your aquarium is crucial for maximizing wealth:
Sell Ocean Mutations:
- Ocean mutations provide higher individual multipliers
- Best for immediate lump-sum cash

Frequently Asked Questions
How long do weather events last in Dive Down?
Weather events typically last for about 3 minutes. Make sure your best fish are equipped in your aquarium before the timer runs out to maximize mutation benefits.
Can I get Weather Mutations without spending Robux?
Yes! Weather events happen naturally on servers over time. The Robux Weather Machine is just an optional shortcut to force an event instantly when you need specific weather conditions.
Do mutations stack with fish rarity?
Absolutely. The mutation multiplier applies to the base stats of the fish. This means a 3.0x Rainbow multiplier on a Mythical fish will yield significantly more cash than the same multiplier on a Common fish.
Can fish have multiple mutations in Dive Down?
No, fish cannot have multiple mutations. Each fish can only have one type of mutation – either one Ocean mutation (Silver, Gold, or Rainbow) or one Weather mutation (Frozen, Shocked, or Chocolate).
What is the best mutation in Dive Down?
Rainbow is currently the best mutation in Dive Down as it has the highest multiplier (3.0x). That’s also why it has the lowest spawn chance out of all the mutations.
How do I start a weather event manually?
To start a weather event, go to any bridge and interact with the weather machine. From there, choose the weather you want to spawn and pay Robux to spawn the event instantly.
Where do Secret fish spawn?
Secret fish have specific spawn locations: Whale spawns in Deep Dark, Whalefish in The Trenches, and Peeber, Rubyfish, and Pebblefish all spawn exclusively in Atlantis.
What equipment should I prioritize for mutation hunting?
Focus on upgrading your O2 tank first for longer dives, then weights for faster descent to deep zones, and finally fins for quick returns to the surface with valuable mutated fish.
Conclusion
Mastering fish mutations in Roblox Dive Down is the ultimate key to building massive wealth and progressing quickly through the game. By understanding the differences between Ocean and Weather mutations, optimizing your equipment and strategies, and focusing on high-value targets, you can dramatically accelerate your progress.
