Need id.

I dont have a picture as ive only seen it yesterday. Its a black invert the size of a silver dollar. Looks like a mollusk and has a small dome. Totaly black no other color. Seemed to be totaly roundish not like a stomatella snail.
Any help would be great.

Could ba a limpet...maybe a Keyhole limpet.....Limpets are mollusks closely related to abalones. Safe.

Thats what i was thinking... But in any case its not in a reef tank so as long as it cant pull down a clown i think its ok.
But if anyone else has a specific id let me know.
