pyramid snails

[cfmx]

We have 6 clams in our tank and most of them have pyramid snails. He have for several months now taken 4 of the clam out of the tank to clean it w/ a tooth brush to get the snails off (the other 2 we clean in the tank since they are attached to rock). But can't seem to rid tank of the problem.
Are there any fish that eat the snail eggs? If we remove the clams from the tank are there other host for these snails to stay alive? If not how long do you think they would need to be out of the tank before putting them back in the tank?
Also any suggestions on how to get 4 inche clam unattached from a rock?

yellow coris wrasses will eat the snails, which is in my opinion good insurance to have in your tank if you want to keep clams.

some wrasses will eat pyrams but the problem is that pyrams feed at night and wrasses sleep at night so at best wrasses will only control pyrams. your best bet is to remove all the clams from the tank every other night(an hour after lights out) and brush the shell very well. if there's any sand under where the clam way remove that also. you will need to do this for 8 weeks(even if you dont see any), then do it once a week for another 8 weeks.

to remove your clams from the rocks, tip them to one side and cut the byssal threads as far away from the clam as you can.
