There are 4 different types of fish rarity in Fishing Clash. Each is being indicated by a lure colour:
- Grey - Common - can be upgraded up to level 10
- Blue - Rare - can be upgraded up to level 9
- Green - Epic - can be upgraded up to level 8
- Purple - Mythical - can be upgraded up to level 7
- Gold - Legendary - currently the rarest lure in the game. Can be upgraded up to level 5
- Red - Event fish - special kind of lures available for a limited amount of time in special events. You can upgrade those lures for free up to level 6.
Each rarity type has a different price for upgrading as well as a chance of finding them in packs.
After upgrading lure to its maximum level you will be able to sell the same lures if you'll get more from packs.
