Clam questions and ID 2 SPS corals....

[newreefer_59]

I posted this a few days back but now have a pic....

I got some live rock (from a fellow reefer) that included a 3" clam - do not know the actual type of clam, but is very cool looking.

I put the rock with clam about 1/2 way up in my 150 gallon tank, so is about a foot from the surface with good flow but not direct flow from one of the tunzes.

Question 1: My bubble tip anenome gets larger by the day, and will move from time-to-time. It is getting close to the clam and seems to kill off the SPS coral as it moves around. Will the anenome harm/kill it?

2: Do I target feed the clam or does it just filter feed?

3: can anyone identify the SPS corals that are attached to the rock.

Many thanks
