If you want to buy better Water Pumps, Auras, and Pets in +1 Drain Water Per Click, you will eventually need a lot of money. One of the best ways to increase your earnings is by filling your aquarium with mutated fish.
Mutated fish are worth much more than normal fish because they come with special multipliers. Some mutations can be found naturally around the map, while others become much easier to find during specific weather events. This guide explains how the mutation system works, how to find mutated fish, and which mutation gives the biggest bonus.
How to Get Mutated Fish in +1 Drain Water Per Click
Getting a mutated fish is fairly simple. You need to explore the different areas of the map and look for fish with a mutation. Once you find one, pick it up before it disappears. Mutated fish can appear across the different areas of the map, so you don’t have to stay in one specific location to find them. There are currently four mutations to look for:
- Gold
- Diamond
- Venom
- Hole
Gold and Diamond fish can appear naturally during normal gameplay. Venom and Hole fish are much harder to find and are connected to specific weather events. Because mutated fish have much higher values, it is worth checking the map regularly instead of only collecting normal fish.
All Mutations in +1 Drain Water Per Click
Each mutation gives a different multiplier to the fish’s value and earning rate. The higher the multiplier, the more money the fish can generate for your aquarium. Here are all four currently available mutations.
1. Gold Mutation
Multiplier: 2x
Gold is one of the easier mutations to find. Gold fish have a gold-colored appearance, making them fairly easy to recognize when you are searching around the map.
You can also identify them by the Gold label displayed above the fish’s name.
The Gold mutation provides a 2x increase to the fish’s sale value and earning rate. While it isn’t the strongest mutation, it can still be useful when you’re starting to build your aquarium.
Gold fish can spawn naturally in all areas of the map, so you don’t need to wait for a special weather event.
2. Diamond Mutation
Multiplier: 5x
Diamond is considerably better than Gold. Fish with this mutation have a bright cyan appearance and display Diamond above their name.
A Diamond fish provides a 5x multiplier to its sale value and earning rate.
Like Gold fish, Diamond fish can spawn naturally throughout the map. However, they are more valuable, so finding them can make a noticeable difference to your earnings.
If you are still working toward the more difficult mutations, Diamond fish are a great option to keep in your aquarium.
3. Venom Mutation
Multiplier: 10x
Venom is where mutations start becoming much more valuable. A fish with the Venom mutation gives a 10x multiplier to its sale value and earning rate.
Venom fish have a bright neon-green appearance, with Venom displayed above their name.
They have a low natural spawn chance, which makes them harder to find than Gold and Diamond fish.
The best way to look for Venom fish is during the Poison weather event. This weather increases the chance of finding Venom mutations by an additional 10%.
The Poison weather event lasts for around 4 minutes, so you should focus on searching for fish while it is active.
4. Hole Mutation
Multiplier: 20x
Hole is currently the strongest mutation among the four listed here.
A fish with the Hole mutation receives a massive 20x multiplier to its sale value and earning rate. These fish have a dark appearance and display Hole above their name.
Hole fish have a low chance of appearing naturally, so finding one outside of its related weather event can be difficult.
The best opportunity to find them is during the Black Hole weather event. This event increases the chance of Hole mutations appearing by 10%.
Black Hole weather lasts for approximately 4 minutes, giving you a short window to search for these extremely valuable fish.
Which Mutation Is the Best?
The Hole mutation is currently the best option because it gives a 20x multiplier.
The mutation ranking from lowest to highest multiplier is:
- Gold: 2x
- Diamond: 5x
- Venom: 10x
- Hole: 20x
This makes Hole fish particularly valuable for players trying to increase their aquarium income as quickly as possible.
However, don’t ignore the other mutations. Gold and Diamond fish are easier to find, while Venom can become much more accessible during the Poison weather event.
How to Find Mutations Faster
If you’re specifically hunting for mutated fish, there are a few things you should keep in mind.
- Check different areas instead of staying in one location.
- Pick up mutated fish as soon as you find them.
- Keep an eye out for Gold and Diamond during normal weather.
- Search for Venom during the Poison weather event.
- Search for Hole during the Black Hole weather event.
- Don’t waste the limited weather-event time searching in only one small area.
- Prioritize Hole and Venom when their related weather events are active.
The weather events are especially important because they give you a better opportunity to find the rarer mutations.
Why Mutated Fish Are Important
Mutations aren’t just cosmetic changes. They directly affect how much money your fish can generate. A normal fish might provide a basic amount of income, while a mutated version of that fish can be worth several times more. This becomes increasingly important as the prices of Water Pumps, Auras, and Pets start getting higher.
For example, a Hole mutation has a 20x multiplier, making it significantly more valuable than a normal fish. Building an aquarium filled with high-value mutations can therefore help you progress much faster.
The mutation system in +1 Drain Water Per Click is an important part of making money efficiently. Gold and Diamond mutations are useful because they can appear naturally, while Venom and Hole become much more interesting during their respective weather events.
If you’re looking for the best possible mutation, focus on getting Hole fish because the 20x multiplier makes them the most valuable option currently available. Just make sure you are ready to search when the Black Hole event appears, since the event only lasts around four minutes.
For general farming, keep collecting every useful mutation you find. Even Gold and Diamond fish can add up and help you afford better upgrades, pets, and equipment.
