pretty rare. But keep looking! You need one to get the regis!
It appears in the seaweed under Sootopolis City.
Relicanth is a Pokemon required to find the 3 Legendary Regis Pokemon. It is found by the underwater entrance of Sootopolis City. Just by the underwater entrance there should be seaweed. Swim around in that seaweed and you will encounter various Pokemon like Clampearl, Chinocho, Tentacool, and Relicanth. Plus some other water types.
Almost everywhere under water. You must know dive. Probably dive near sootopolis and since Relicanth is rare, it may pop up after awhile going through the seaweed.
you will find relicanth underground under sotopolis city (note relicanth is super rare it will take for ever to find
under water of sootopolis city Relicanth is a rare (ultra rare ) fish Pokemon found only under water at route 124 or route 126. you need to know dive. have a lot of dive balls with you.

Under water under sootopolis city.
Go to sootopolis. Use dive to get to a underwater cavern. hen exit the cavern, and you should see patches of weeds, or grass, on the floor. Relicanth will appear in the grass under the ocean. He's rare, though, so it may take you some time to find him.
You can find a relicanth under the sea by sootopolish city or again under the sea on the way to mossdeep city and relicanth's are very hard to find unless u have sweet scent or white flute but it dose take a lot of time to get
I hear you can find it by diving near sootopolis city and look in the grass, but they're rare so you'll have to have a lot a patients. also try routes 124 and 126 i heard they have promise. Deity Link- what i did was get a Pokemon at level 35 EXACTLY and get a ton of max repels go under sootopolis and go around and use the max repel with the level 35 Pokemon in the front then go around and it will flush out a lot of the Pokemon you don't want so then you will be left with clamperl the possible surskit and relicanth to see i saw it first three Pokemon
