Snail/Whelk ID Please?

[Ratvan]

Spotted this today, not added anything for about a Month so I guess it has come in on the Zoa rock that I purchased a while back, struggling for a good photo due to size (roughly 0.5-0.75mm)

Best i can do with Zoom

Looks like a dove snail (Columbellidae sp.). These beneficial snails sometimes hitchhike on live rock and are often misidentified as Strombus maculatus. In my system, they have been great algae grazers (their small size allows them to access macroalgae fronds and crevices) and prolific breeders.

Adults:

Juvenile:

Egg cases (center of an egg case will develop a circular hole after the juveniles have hatched):

Those were both my initial thoughts, glad it's something prolific as I have not had great success with macro due to algae growth on thr macroalage itself. Might give them another go if I have these
