Brought some snails home from florida OOPS carniverous?

Does anyone know about snails and if these snails with the little daggers coming out of the front can hurt my fish or blennys ? I just watched a video on youtube that has me freaked out.... http://www.youtube.com/watch?v=mtPVgW3rLqE I'm guessing i should be worried.... are these only really large ones or should i worry even about the smallers ones :( yikes I thought i was doign myself a favor by taking some of these home to help my clean up crew... i'm having some algae problems :(
 
This is very true... Some of them are regular algae eaters.. some are sand sifters and then of course there re these. I"m wondering if there is a way to distingueish which are which

Where in Fla did you collect these.?? We collect nassarius snails down south here and they have "daggers" out the front....of course these are the good kind. A picture of the offending creature would help.
