key hole limpet?

[karsseboom]

Somthing has been eating my sps and I know its not aefw or red bugs. I have a very good eye when it comes to this stuff and know its nots that. I have been goin through this random spots on sps that looks like somthings eating them and not stn. Today I snapped a pic of this and think it might be limpets


bad pic but it was hard to get...if you look close on the bottom of the coral you can see a tiny little black spot which to me looks like a limpet but not sure

It does indeed look like a key hole limpet.

Although I find them to be such a great discovery in a tank I would remove it if you are having issues with an unknown cause of decline or predation of SPS.

Not all limpets (especially key hole) are reef safe.
