If you're looking to explore the oceans and live among the fish, then I've got a bunch of great Minecraft Coral Reef Seeds for you! I've sailed vast Warm Ocean biomes and braved treacherous seas to discover the best Coral Reefs in Minecraft and create this convenient list.
These seeds work for both Bedrock and Java, so you should be able to find something you like on any platform. While world generation works similarly between the two versions, they still generate structures at different locations. Because of this, I have provided helpful lists of key locations for both versions of each seed!
Best Minecraft 1.21 Coral Reef Seeds
Get ready for a life of tropical living.
Personal Reef
Seed: 5059114762744265000
You'll be surrounded by colorful coral in this world. You'll start only a short swim away from a large Coral Reef, but what is even more enticing are the two smaller reefs around it. The first is next to Spawn while the second is in an isolated portion of the ocean next to a Desert Village. These smaller reefs are perfect for players who want to live within a coral reef without getting lost as easily as you would in larger coral patches.

Coral Peninsula

A peninsula made of Desert, Jungle, and Stony Shores biomes juts into this world's Coral Reef. The Jungle biome provides the wood needed for survival while the Stony Shores is home to some basic ores. It's a lovely combination of biomes that will get you started off well so you can explore the reef comfortably. Java players will find a Desert Village along the reef while Bedrock players will have three chests of buried treasure around Spawn.

Badlands and Desert biomes border this giant Coral Reef. The ocean containing this reef is fairly large and is even home to a few small Mushroom islands southeast of Spawn. Most of the structures in this seed are hidden within the Coral Reef itself. You'll find mainly Warm Ocean Ruins and shipwrecks, but there are a few Trial Chambers hidden beneath it as well.

Coral Lake
Seed: 4903410334506783867

Fields of Coral

Most Coral Reefs are in Warm Oceans on the edge of Desert biomes. This one is no exception. Java players will mainly find Warm Ocean Ruins and shipwrecks in the Coral Reef itself while Bedrock players will also have a Desert Village near Spawn. Since you spawn next to the reef, you'll be able to enjoy it immediately.

Coral Beginnings
Seed: -3600559789931108364
A Coral Reef is a great biome to build a base in. Since you'll be underwater, it'll be difficult for many mobs and even players to find and attack you. The Coral can be used to cover the top of your base and hide it from any prying eyes. If you're feeling fancy or are confident in your defensive abilities, you can make a larger, flashier base like something out of Subnautica.

Tropical Coral Seas
Seed: 5941544289008647838
These Coral Seas are directly off the coast you begin on in this Minecraft world. The sea begins with a lone yellow coral block, giving you a silly sneak peek of the Coral Reef a little further out. To go with the bright colors of the Coral Reef, players will encounter a Lush Cave a short walk away. Java players will have a mineshaft in this cave, but players of both versions will have a Trial Chamber nearby as well.

Giant Coral Reef
Seed: -5359898961167250079
Sometimes bigger is better. This Coral Reef is only a brief trip from the world's beginning and expands over a massive Warm Ocean biome within a Desert. You'll find all the coral and tropical fish you could ever dream of. Additionally, you can wander around the reef to find various Desert-specific structures like villages and temples.

Coral Ravine
Seed: 8225517119173891146
Coral tends to only cover a single layer in oceans in Minecraft, maybe two layers for luckier players. This Coral Reef stands above the rest because the Coral has grown in an underwater ravine at the start of the reef! Go spelunking underwater surrounded by the brilliant hues of blue, red, and pink coral blocks. It's a sight that every Minecrafter can appreciate.

If you've ever wanted to jump straight into a Coral Reef from a sandy beach, this seed will make your dreams come true. All players will find shipwrecks and Warm Ocean Ruins scattered in the ocean around the reef. Java players will also find a Desert Village and a ruined portal. Instead of these, Bedrock players will have a Desert Temple nearby.

Coral Hideaway
Seed: 3041418834540870761
This Coral Reef is perfect for building a hidden base to get away from the rest of the world. The section of the reef closest to shore dips down into the sand, providing an easy place to hide from anyone above the water. The reef expands out from the edge of the Desert and is filled with plenty of colorful tropical fish.

Oasis Reef
Seed: -6073716221727513421
When we think of a Desert oasis, typically we think of swaying trees, green grass, and a beautiful blue source of water. This Minecraft seed takes a twist on the Desert Oasis by turning it into a colorful Coral Reef. Small tropical fish can be found swimming about while coral acts like trees on the lakebed. Java players will find a set of Warm Ocean Ruins hidden within the coral. In contrast, Bedrock players will have a Desert Temple near the lake's edge.

Multi-Layer Coral Reef
Seed: -3135873002303195014
This seed begins in a Wooded Badlands biome next to the ocean. The ocean has a shallower area near the badlands that drops down as you swim further out into the sea. Both the shallow and deep areas are filled with coral, making this a two-layer Coral Reef. This includes a few pieces of coral that have grown within the nearby underwater ravine.

The Coral Reef in this seed covers over 1,000 blocks, ranging from the area right next to Spawn to a Mushroom Island and even further beyond that.
