Bumble bee snails - reef safe?

[al0ha]

i have 3 bumble bee snails and some zoa/paly frags. i read online with some saying they're NOT reef safe and some say they are....just wanna hear from your experiences. thanks!

they are fine sand sifters... however if they are hungry they will eat other snails... which makes them not exactly reef safe.
but since there really is no such thing as reef safe... add them in.

I got bumbles i got at manhattan aquariums , and they do nothing but clean, reef safe , especialy if your tanks got six months or more , they will be just fine
