How to Get Mutated Fish in Net a Fish
There are two ways to get mutated fish in Net a Fish: catch mutated fish from the river and fusion. Fish with mutations will spawn in the river, and you can catch them by casting your net. Here are a few things that you can do to increase the spawn rate and chance of mutated fish.
- Buy the Mutation Magnet Upgrades: From the Upgrades menu, click on Fishing and scroll down to find the Mutation Magnet. Purchase it and keep upgrading it regularly to increase the chance of catching mutated fish.
- Wave Rush, Lucky Tide, and Shimmer Surge: Certain Net a Fish Events increase the chances of catching mutated fish. Actively play during Wave Rush, Lucky Tide, and Shimmer Surge events to catch more mutated fish.
- Use Glitter Lure, Starlight Worm, or Phoenix Feather: Use any of these three baits to increase your chances of getting fish with mutations. You will have to complete certain Rebirths to unlock these baits at the Bait Shop.

Apart from catching them from the sea, you can also get mutated fish by fusing duplicate fish. Here’s how that works:
- Fuse 10 Normal Fish to get 1 Shiny Fish.
- Fuse 8 Shiny Fish to get 1 Gold Fish.
- Fuse 6 Gold Fish to get 1 Crystal Fish.
- Fuse 4 Crystal Fish to get 1 Glitched Fish.
- Fuse 3 Glitched Fish to get 1 Rainbow Fish.
- Fuse 2 Rainbow Fish to get 1 Starlit Fish.
