If you use dive outside Sootopolis, there will be seaweed patches where you will normally find clampearl. Just surf around there for a while. When I caught my first relicanth, I had tried searching for about an hour, and then gave up. When I came back I had caught all the regis, and I came across a relicanth almost immediately. I dont know if this is a coincidence or not, but what i do know is there is only 2% chance of finding one normally.
no you do not have to catch a relicanth to get a rayquaza
You can catch it when you use dive.
you find it underwater
To catch relicanth use Hypnosis by Gengar and get lots of Dive Balls
You can't catch Relicanth. You have to trade from Ruby, Emerald, Sapphire or any other game that has him captured.
No only in ruby and sapphire and emerald.
underwater routes 124-126,but rare.
Underwater near sootopolis city its rare though.

You can see and catch Relicanth under the water just outside Sootopilis(spl?) City, in the mossy grass.
