Can someone ID this snail?

[eli@fijireefrock.com]

It is Columbellid snail as I have them in the hundreds in my tank and yes they are good tank mate to SPS,LPS and softies,I never had any issues with them,theu are fun to watch sometimes as they hang off the rocks,and you see their egg sack on the glass as it is very neat.To be honest I have no algae in my tanks and think they might be part of that reason as I have no cleaners in my tanks.Hope that helps.
