Fish

Fish are the core resource in Abyss on Roblox. Every biome has its own set of species, ranging from Common catches worth a few dollars per kilogram to Mythical boss drops that require serious firepower to obtain. This guide covers all 39 fish and creatures in the game, including their rarity, weight ranges, sell prices, behavior, and spawn locations.

How Fish Work in Abyss

Fish are caught using your gun while exploring underwater biomes. Each fish has a rarity tier (Common, Uncommon, Rare, Epic, Legendary, Mythical), a behavior type (Passive or Aggressive), and a weight range that determines how much cash you earn when selling. Passive fish won't fight back; aggressive fish will attack you on sight.

Fish value is calculated as weight x price per kilogram, and can be further multiplied by mutations. Your tube's weight capacity limits how many fish you can carry per trip.

Forgotten Deep Fish

The starting biome. All fish here are on the lower end of rarity, making it a good grinding spot for new players.

Fish	Rarity	Behaviour	Weight	Price	Location
Blue Tang	Common	Passive	0.5kg - 1.0kg	$14/kg	Forgotten Deep, Ocean
Clownfish	Common	Passive	1kg - 2kg	$12/kg	Forgotten Deep, Ocean
Tang	Common	Passive	0.5kg - 1kg	$12/kg	Forgotten Deep
Pufferfish	Uncommon	Passive	2kg - 4kg	$13/kg	Forgotten Deep, Ocean
Salmon	Uncommon	Passive	4kg - 8kg	$9/kg	Forgotten Deep, Ocean
Lionfish	Rare	Aggressive	2kg - 6kg	$20/kg	Forgotten Deep
Mahi Mahi	Rare	Passive	8kg - 20kg	$8/kg	Forgotten Deep
Barracuda	Epic	Aggressive	6kg - 12kg	$20/kg	Forgotten Deep

Best Fish to Farm in Forgotten Deep

Barracuda offers the highest value here at $20/kg with a 6-12kg weight range, meaning a single catch can net $120-$240 before mutations. Mahi Mahi has the highest raw weight (up to 20kg) but a lower price per kilogram. For early-game players, Salmon is reliable passive income with no danger.

Ocean Fish

The Ocean connects Forgotten Deep to other biomes. It shares several species with Forgotten Deep but adds unique Rare and Legendary catches.

Fish	Rarity	Behaviour	Weight	Price	Location
Blue Tang	Common	Passive	0.5kg - 1.0kg	$14/kg	Forgotten Deep, Ocean
Clownfish	Common	Passive	1kg - 2kg	$12/kg	Forgotten Deep, Ocean
Pufferfish	Uncommon	Passive	2kg - 4kg	$13/kg	Forgotten Deep, Ocean
Salmon	Uncommon	Passive	4kg - 8kg	$9/kg	Forgotten Deep, Ocean
Sea Horse	Rare	Passive	?	?	Ocean
Blobfish	Rare	Passive	?	?	Ocean
Piranha	Rare	Aggressive	?	?	Ocean
Shark	Epic	Aggressive	?	?	Ocean, Ancient Sands
Sailfish	Epic	Aggressive	?	?	Ocean, Spirit Roots
Bluefin Tuna	Legendary	?	?	?	Ocean

Ocean Fishing Tips

The Ocean is where aggro fish become more common. Shark and Sailfish are both Epic-tier aggressive species, so bring a gun with decent damage before heading out. Bluefin Tuna is Legendary and one of the rarer catches here.

Ancient Sands Fish

Ancient Sands features sandy, low-visibility waters and several exclusive species. This is the first biome with Legendary creatures.

Fish	Rarity	Behaviour	Weight	Price	Location
Pompano	Common	Passive	?	$15/kg	Ancient Sands
Cod	Uncommon	Passive	?	?	Ancient Sands
Blackfin Tuna	Uncommon	Passive	?	?	Ancient Sands

Cavefish	Epic	Passive	?	?	Ancient Sands
Shark	Epic	Aggressive	?	?	Ocean, Ancient Sands
Bigmouthfish	Legendary	Passive	?	?	Ancient Sands
Ancient Shark	Legendary	Aggressive	?	?	Ancient Sands

Ancient Sands Exclusive Species

Ancient Shark is the headline creature here -- a Legendary aggressive fish described as "a massive shark said to have lived for centuries." Bigmouthfish is the opposite: Legendary but completely passive. It's required for Suspicious Fisher's Quest 1 (catch 3 Bigmouthfish). Cavefish is described as "big, flat, and kinda derpy."

Spirit Roots Fish

Spirit Roots is the largest biome and requires completing Isolde's quests to fully access. It has the most diverse roster of fish, including several Legendary and Mythical species.

Fish	Rarity	Behaviour	Weight	Price	Location
Pacific Fanfish	Common	Passive	?	?	Spirit Roots
Jellyfish	Uncommon	Passive	?	?	Spirit Roots
Napoleon	Uncommon	Passive	?	?	Spirit Roots

Drop	Rarity	Description
Dragonfish Head	Mythical	A massive Dragonfish head.
Dragonfish Meat	Mythical	Fresh cuts of Dragonfish meat.
Whale Head	Legendary	A massive Whale head.
Whale Meat	Legendary	Fresh cuts of Whale meat.

These drops are required for late-game quests, particularly Victor's Quest 6 (Sacrifice of Giants) which needs 3 Whale Meat, and Victor's Quest 7 (The Soul of Roots) which needs 2 Whale Heads and 6 Whale Meat.

Angler Cave Fish

Angler Cave is a hidden area unlocked after completing the Lost Captain's quest chain. It's small, dark, and contains only four fish -- but includes the Mythical King Anglerfish.

Fish	Rarity	Behaviour	Weight	Price	Location
Blobfish	Rare	Passive	?	?	Ocean
Piranha	Rare	Aggressive	?	?	Ocean
Anglerfish	Rare	?	?	?	Angler Cave
King Anglerfish	Mythical	Aggressive	?	?	Angler Cave

King Anglerfish Drops

Like the Dragonfish and Whale, the King Anglerfish drops Mythical-tier parts:

Fish Sell Prices: Which Fish Make the Most Money?

For fish with confirmed pricing data, here's a value comparison:

Fish	Price/kg	Max Weight	Max Single Catch Value	Rarity
Barracuda	$20/kg	12kg	$240	Epic
Lionfish	$20/kg	6kg	$120	Rare
Pompano	$15/kg	?	?	Common

Remember: these values can be massively boosted with mutations. An Abyssal Barracuda (8.5x multiplier) at max weight would be worth $2,040 per catch.

How Mutations Affect Fish Value

Every fish in Abyss has a chance to spawn with a mutation that changes its appearance and multiplies its sell value. The multiplier applies directly to the base price. See the full Mutations guide for all 21 mutation types, but the key ones for fishing profit:

Poop (0.33x) -- Actually reduces value. Avoid selling these.
Gold / Negative (2x) -- Doubles the base price.
Abyssal (8.5x) -- The highest multiplier in the game.
