Keyhole Limpet?? Is this snail reef safe?

[elmatth1]

I've been seeing alot more of these snails lately, especially at night time. It seems they have been reproducing like crazy! I've had a hard time identifying them, so I thought maybe you guys could help. Here's a couple of pictures... they are very small, only about 1/8-1/4 inch in length and have an off white color

any help with the identification would be appreciated.

It's a limpet, and if there's a hole at the apex of the shell it's a keyhole limpet. Lots of species fall into this category. Harmless grazer unless it's a species that eats corallines. Unfortunately the picture isn't good enough to do a better id.

I don't think there's a hole in the top, but I could be wrong... they are all really small, so it's hard to see. Sorry I can't post a clearer picture, that's about as close and clear as my digital camera would allow.

I have some that like to eat my little ball sponges that come in on live rock . I have seen one eat hydroids as well .
