To catch Grimer in Pokemon Ruby, you have to beat Wattson of Mauville City. Once you beat him, head north and use rock smash on the small boulder in your way. Climb up a set of stairs and battle a few mountain climbers. Once you have the trainers out of the way, enter the cave enterance to your far left. You will find yourself inside a small tunnel. Mainly, you will only find Slugma, Torokoal, Machop, and Koffing there, but if you search hard enough, sooner or later you'll run into a Grimer. Remember not to use Psychic attacks when trying to catch a Grimer; psychic attacks are super effective and they might knock it out.
Grimer can be found in the Pokemon mansion on Cinnibar Island, where the 7th gym is located. Otherwise it is possible to fish one out of the pond in Celedon city with a Super Rod. (note that they are extremely rare if fished)
To catch grimer in Pokemon Ruby you need to go toFiery Path. It's a common Pokemon there so you need to be patient, it's actually just 2% rate to find it.
Fiery Path is in Route 113. Walk around until you find it. You will find it in lvl 14, 15 and 16 if you find it.
Good luck! :)

It takes a while to find them, but you will find them in the mansion which is on Cinnibar Island.
The tunnel north of Mauville, to the left of the Desert and Southeast of Lavadridge. There's also Numels, Torkoals and Koffings
