I was doing some research last night on a unknown hitchiker i have and from the looks of it its a limpet snail not 100% sure its a keyhole.if indeed it is a keyhole how would i go about removing these bugers,as i here there near impossible to pry off the rockwork..??

What do you have in the tank that you would want to remove it?
You just pick him up and remove him. They are not that hard to remove. Is he huge or something?
Do the removal in one swoop, he'll try to hunker down if your just touching on him first. If he's on an uneven surface, like a rock, he'll be easier to remove. But they really aren't that hard. It's things like big ole chitons and abalones that are difficult to remove when they "hunker".
If you lived closely he would have a room in my tanks.

.I have some ric's,zoa's pulsing xenia and other various mushrooms but it will be mainly a sps dominated tank.its not just one i counted 20 last night and thats just on one side of my tank,but there supper small like the size of an eraser on a pencil maybe smaller.the reason im nervous is i heard there not just herbivores and they have been known too devoire the skin off of corals

I've never had a problem with the small ones. I know what the stuff says out there, but I think it is more of us not being able to ID the trouble-makers.
Maybe someone can give some real life experience of them eating corals.... not what they've heard from a friend of a friend of a friend.
The small ones have not created in trouble in my tanks not in the tanks of the people I've shared them with which is about 10 people now.

But we don't know if it was a different species of limpet or not. I can put up a pic of mine that did not touch coral. Can you get a picture of yours? Maybe send me a couple of limpet shells? That the "real" way to ID their species... by looking at the inside of their shell. I probably won't be able to ID it, but I could at least say if they were like mine or not. I wonder if Bang Guy has a picture of his. Maybe send him a PM so he can give some input as well.
Maybe that would be something I should work on... collecting shells of different limpet species.... Hmmmmm.

I should have a chance to post some pictures tonight.
Keyhole Limpets are not true limpets, they are actually closer related to Abalone. I've had them peel the skin off a Toadstool but it didn't really do any harm. They are algae eating machines though, they can carve a path through Bryopsis and Hair Algae.
If it were me I would leave them in until they actually cause a problem.

Don't know if this helps. I've had the ones shown in Bang Guy's 3rd pic, as long as I've had a sw tank(about 6 years or so) and have never had a problem!!

here is one that we have in our tank and in the sump and never seen them bother anything and they stay mostly on the glass and the largest i have seen these get are about 1/4" and they multiply all the time and seem to have a short life span as i see alot of empty shells

If they do not have the hole at the apex of the cone (the keyhole) then they are probably true limpets. Limpets are strict herbivores.
Another possibility is that you have Stomatella Snails, also beneficial herbivores but mostly only eat Diatoms.
