Best Minecraft Coral Reef Seeds – 1.21, Bedrock & Java (2024)

Live in a vibrant, colorful ocean!

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.

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.

Sometimes bigger is better. This Coral Reef is only a brief trip from the world's beginning and expands over a massive Warm Ocean 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.

This Coral Reef contains several ruins structures for players to explore, including shipwrecks and Warm Ocean Ruins. It's next to spawn, giving players early access to buried treasure and potentially even Sniffer eggs! Just remember to mine copper in the desert for brushes first.

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.

If an endless Coral Reef is what you want, an endless Coral Reef is what you'll get! 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. It's perfect for crafting a hidden base out of coral as no one would even know where to look. It's also great for any underwater-themed adventure games.

Tropical fish lovers, this one is for you. The Coral Reef is large and located right next to Spawn. As soon as I entered the world, I saw dozens of tropical fish swimming through the reef. It covers the shallow and deeper parts of the ocean, providing all players with an endless array of bright colors and cute fish.

Spawn in this world is set on a beautiful, crescent-shaped windswept island. If you follow the Coral Reef near Spawn, it will lead you to a small Mushroom Island! If that's not enough mushrooms for you, there is a larger one beyond the reef's edge.

Contained Coral

Seed: -8777635791071504639

This patch of coral is separated from the rest of the ocean and is contained by a ring of sand. Players of both versions will have a Desert Village in the surrounding area. Whether these villagers moved here for the coral or were here before it ever arrived, they make good use of it in their everyday lives. You're more than welcome to harvest and use it as well. If you'd prefer to leave this patch as-is, there is more coral beyond the sand that you can utilize.

This seed is a beautiful one that guarantees a Coral Reef from the start. The Coral Reef is small but very densely populated with coral, tropical fish, and even squids. Structures can be found in the surrounding ocean, plus a second patch of Coral Reef can be found not far off from this one. If you want to live a colorful ocean life, make sure to try out this seed!

Lava falls blend with the waterfalls and Coral Reef of this seed. Unbeknownst to many, the cave within the wall is actually a Lush Cave! An Acacia tree can be found peeking out of the water a few hundred blocks away, revealing the existence of the cave. You could turn it into your home or build a base within the reef itself.

This Coral Reef contains multiple mountain-like islands that give it a very dramatic appearance. The starting island contains a Stony Shores biome with plenty of iron and coal, and the mainland in the distance has plenty of trees. The hardest part is just climbing to the top of each island.
