These mutations add a layer of complexity to fishing, especially when you hook something rare. With many different mutations, it can be quite overwhelming to know which ones are what.

How to Get Mutated Fish in Abyss Roblox
Mutated fish spawn randomly when fishing in Abyss Roblox, and each mutation has its own hidden rarity. Higher-value mutations like Abyssal, Angelic, and Shadow are significantly rarer than common ones such as Rock or Moss.
Using better fishing gear increases your overall fishing efficiency, giving you better chances at catching these fish. There is also a higher mutation rate when fishing in deeper or more dangerous areas, though mutations ultimately remain RNG-based. The key is volume, since more catches mean more chances to land rare mutations.
