A ghost appears if you don't have a Silph Scope. You can't catch it. Continue on to the next town and go into the Casino place (with all the slot machines). Talk to the grunt and battle him. Examine the poster and go down the hidden stairway. Make your way to the boss, Giovanni. He will battle u and if u win u will be rewarded with a silph scope! Go back to the tower and the ghosts are now gastlys, marowak and other dark pokemons. Go to the very top and save the man. You'll battle 3 Team Rocket Grunts. The guy will give u a poke Flute. Use it to wake up snorlax and battle it. Snorlax is hard to catch but he is very helpful in catching legendary birds like Zapdos.
At the end of the Ghost Tower you'll find a ghost which is the dead mother of the Cubone in Mr. Fuji's house.
shadow ball is the strongest ghost TM
You cannot catch the ghost in the Pokemon Tower until you reveal what it really is.
Technically yes and no a GHOST can't be captured but with the silph scope you can reveal the Pokemon's true identity which is gastly which is a ghost Pokemon so that makes sense.
HOW AM I SUPOSED TO KNOW ASK SOMEONE ELSE
yes its really a Pokemon only you need a special item to see them once you have it go back and the ghost is now a Pokemon
Dark attacks. I suggest something common such as bite which a lot of the early pokemon can learn
Haunter.... There isn't that many ghost types in firered besides the Gastly line which you can find in Lavender Town's Pokemon Tower
You need the Silph Scope from the Rocket base in Celadon City, that will automatically reveal the Lv 30 ghost as a Marowak.

Work your way to the top of the Pokemon Ghost Tower and defeat the Rocket Grunts.
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
There is no Pokemon convention in firered.
