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 created 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, however, 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 1.20 Coral Reef Seeds
Stonewall Reef
Seed: -355846066655904585
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.

Coral Mounds
Seed: 8437899708359357037
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.

Abandoned Reef
Seed: 2318991752058972794
The inhabitants of this reef disappeared long ago, leaving behind a ruined portal, a shipwreck, and an abandoned Desert Village. Bringing life back to this Coral Reef is no easy task, but it's not impossible. The remnants of the shipwreck can be used to rebuild the town while the portal can be reconstructed from its fragments. Once it's restored to its former glory, villagers can be brought in from all over the Desert to repopulate it.

Coral Jungle Coast
Seed: -1161329451001867553
Spawn is set on the boundary line between a Forest biome and a Jungle biome. Venturing deeper into the Jungle biome will lead you to a beach and then a Warm Ocean containing a large Coral Reef. It's the perfect seed to make an aquatic base using the new Bamboo blocks. You could even use stripped bamboo to make a small tiki hut on the beach!

Desert Coral Peninsula
Seed: -745873239446713484
This world begins in a large Desert surrounded by Badlands. Instead of heading south into the Badlands, walk north through the Desert to reach a stunning Coral Reef! A peninsula juts into the water, splitting the Coral Reef in two. What's even more unique is the tiny Mangrove Swamp growing in the center of the peninsula, which serves as the only naturally growing wood source in the area.

Mini Island Reef
Seed: -6473062580896488653
Spawn is set on a Jungle island a little ways away from the mainland. A small Coral Reef exists right beneath the taller edge of the island, with a gap at the water's surface revealing a Lush Cave beneath the island. A larger Coral Reef can be seen in the distance and is only a short boat ride away.

Surrounded by Coral
Seed: 43137723971174344
Bordered on all sides by Warm Oceans, this series of Deserts and Badlands will give you access to all the coral you can handle. Depending on the version, this is either a sprawling desert with structures and ruins galore, or a wasteland for you to explore

Floating Oasis
Seed: 5382294136739163134
Depending on your version, this seed gives you two different experiences. On Java, this features a floating village, precariously sitting next to a huge Desert bordered by a Coral Reef. On Bedrock, this is a vast Coral Reef, with only shipwrecks and ruins to behold. Either way, it's pretty spectacular!

Seed: 3935656003807081250
A vast and bountiful Coral Reef bringing life to a desert causeway. The fish, dolphins, and other creatures living in the Coral Reef provide the lifeblood of this whole area. If we were going to set up an underwater base, we'd do it here!

Coral Crater
Seed: 599282705
A crater in the Badlands with a Coral Reef inside and exposed Lush Caves. This is one of the most unique and incredible seeds we've ever seen, and we want to come back to it again and again. The reef continues beyond the crater, but the beginning area is just so incredible that you'll never want to leave!

Mini Coral Mesa
Seed: -1845039371514902489
A tiny outcrop of terracotta next to a mini Coral Reef that expands into a full reef further out. This is a huge conflux of biomes, with a sprawling Jungle and plenty of other areas to explore nearby. This is definitely an exotic seed that doesn't have many of the vanilla biomes in easy reach, so start here at your own risk!

Jungle Beach on a Coral Ocean
Seed: 168764718018804
Just as the name implies, your spawn in this seed is on a Beach encompassing a Jungle Biome. Right off the beach and within view of Spawn are several branches of Coral Reef that extend into the ocean as far as the eye can see. When you take wood from the Jungle and fashion a boat, you'll find a large Warm Ocean biome filled with Coral Reefs that spread out past the horizon!

Coral Badlands Dive
Seed: 7850875
This is a spectacular seed that fulfills your search for a myriad of different rare biomes—all at Spawn! While the Coral Reef in this seed isn't large, it deserves special mention because of how convenient the seed is and the unique world generation of the Coral Reef. You spawn near a Jungle Biome (rare) that is home to a Lush Cave (rarer), and can walk to the Wooded Badlands island (rarest) to take a dive into the majestic Coral Reef surrounding it!

Badlands, Goodwaters
Seed: 14000003
You spawn in the Badlands on this seed, which is one of the rarer and more majestic biomes in Minecraft. But, you can ignore the beauty of the red mountains and look toward the ocean to see the beautiful Coral Reef coast a couple dozen blocks away from Spawn. If you follow the trail of Coral Reef, you will eventually reach one of the largest Coral Reefs you've ever seen.

The Reeft Between Worlds
Seed: 11000042
As you can see from the image, this seed spawns you near a Coral Reef that spreads across a Warm Ocean biome near a massive Mangrove Swamp and a Mushroom Island. This is a rare occurrence in world generation, so it is a perfect world to start with if you want to appreciate the best that Minecraft has to offer. You also spawn next to a Badlands biome, and several Shipwrecks are hidden in the Coral Reef for you to discover!
