Update: We last updated this Fish It Mutations tier list on November 18th, 2025.
Catching regular fish in Fish It is an easy task. All you need to do is get yourself a fishing rod, pitch your line, and wait for a creature to take the bait. However, it requires a little bit of luck for you to reel in a fish with a mutation. Such creatures not only look different than their regular variants but also sell for a whole lot more cash. But not every mutation is equally valuable. Hence, this article presents a Fish It mutations tier list to help you pick the best ones out of the lot.
The Best Fish It Mutations Tier List
Before moving forward, it is worth noting that the tier list is divided into S, A, B, and C tiers. Naturally, all the mutations under the S tier are the best and sell for the most amount of money. Their value decreases with each tier, and all the mutations in the C tier are very basic. Now, let us move on to the tier list.
| Tiers | Mutations |
|---|---|
| S | Gemstone, Midnight, Galaxy |
| A | Lightning, Radioactive |
| B | Fairy, Ghost |
| C | Stone, Frozen |
