The sonar blinked at 2 a.m. and a fish with red eyes floated past my crosshair — profit or a trap, I couldn’t tell. You know that sudden ping of possibility when a rare mutation flashes by; it hooks you harder than any bait. I spent weeks logging spawns, server hopping, and testing radars so you don’t have to guess which mutations actually move the needle.
I write guides for players who want fewer surprises and more reliable runs. Below you’ll find every mutation, where it spawns, and the exact multipliers so you can plan runs, pick gear, and game the market on Roblox’s Abyss without blind faith.

If you stare at a spawn through Richard’s radar you start to know the signatures — All Abyss Mutations Explained
I treat each mutation as a signal: color, particles, and region. You can use these cues to pick targets, save ammo, and decide when server hopping is worth it.
Poop
Worst-tier mutation. It reduces sell value to 0.33x. Keep one if you collect oddities, otherwise don’t waste inventory space on these.
Rock
Matte, rough texture that hides on similarly colored fish. It’s a 1x multiplier — neutral value. Use your radar at Forgotten Deep to spot it faster.
Coral
Blue and dull red tones. Easy to spot and common — 1.1x. Useful early-game for quest progress and steady income.
Moss
Green, stony appearance — 1.1x. Often around Forgotten Deep; pair with a mid-tier gun for reliable clears.
Metal
Silver sheen makes metal blends tricky on silver-colored species — 1.2x. Radar saves time here.
Sand
Ancient Sands only — 1.25x. If you hunt there, bring ammo that pierces sand-camouflaged targets.
Albino
Pale white and obvious at range — 1.3x. Rare, but great for quest checks and steady premiums.
Transparent
See-through bodies with a faint shimmer — 1.35x. Required for some Morveth quests; count them when you pass.
Cactus
Ancient Sands exclusive — green-yellow palette and 1.45x. Good mid-tier yield.
Spirit
Spirit Roots only — transparent greenish glow — 1.7x. Rare enough to justify a dedicated route.
Fossil
Ancient Sands exclusive — skeletal texture — 1.75x. Valuable for collectors and bone drops but don’t expect guaranteed bone yields per catch.
Golden
Golden fish have dollar particle effects and pay 2.0x. They stand out like a neon sign in fog — worth the chase when you find one on a spawn list.
Negative
Color inversion makes them pop against the usual palette — 2.0x. Easy visual cue if you hunt visually.
Fairy
Spirit Roots exclusive — glowing pink with particles — 2.3x. High value for targeted runs when you need quest items or a revenue spike.
Invisible
Faint outlines only — 2.4x. Hard to spot but lucrative; use radar sweeps and listen for sonar blips.
Neon
Glowing bodies and easy targeting — 2.8x. Great for players who prefer visible, quick-money runs.
Ultraviolet
Purple-transparent with clear outlines — 3.6x. One of the better general-purpose multipliers for mixed runs.
Rooted
Spirit Roots only, pale green particles — 4.2x. Extremely rare; plan a dedicated run if your goal is high yield.
Shadow
Transparent black body, red eyes — 6.66x. Less rare than Angelic or Abyssal, which makes it a smart target for profit runs. Finding one is like striking a lucky vein of ore.
Angelic
Bright yellow, opposite of Shadow — 7.77x. Extremely rare and worth preserving rather than quick-selling if you value collector status.
Abyssal
Deep blue with glowing parts — 8.5x. The highest standard multiplier; if you get one, many players server hop just to chase this tier.
Cupid
Valentine’s event — pink shades with heart particles — 1.4x. Useful for the Big Boss quest.
Lonely
Valentine’s event — bright pink with hearts — 2.0x. Rare and often hunted during limited windows.
What are the rarest mutations in Abyss?
Abyssal, Angelic, and Shadow sit at the top of rarity lists. Shadow is a sweet spot: rarer than the mid-tiers but found more often than Abyssal or Angelic, which is why many players target it for steady profits.
Do mutations affect fish stats besides money?
Yes. Mutations change weight and speed in addition to sale value. That affects quest progress, boss mechanics, and how quickly a fish reaches escape range — so factor those stats into route planning.
Quick operational tips: use Richard’s radar at Forgotten Deep for early detection; server hop if you’re hunting the highest multipliers; bring appropriate guns for region-specific camo (Ancient Sands vs Spirit Roots). I learned these patterns the hard way; you can shortcut hours of trial by focusing on the visual cues above.
Which mutation would you rather chase next — the reliable Shadow runs or the lottery ticket Abyssal finds?
