I can't figure out for the life of me what's slowly eating my zoas.... just when I thought I had it pinpointed to be amphipods, I see these snails all over a zoa frag that i separated from the display 5days ago. They were right ontop where the frag was, 4 or 5 of them, by the time I got my phone they scurried to the underside of the plug. Could these be eating them too? Amphipods and these snail lookin things are the only thing on the zoas at night. I added 2 wrasses (yellow coris and red fairy) there has been a substantial decline in the # of pods in the 75g. There is also a pair of mandarins w/ the wrasses and a baby seahorse in the fuge. Does anyone have any experience with amphipods or snails killing zoas? Everything else in the tank is doing wonderful. Been dealing with this problem for 6months on and off,any help or suggestions will be appreciated. Thanks

Any asterina stars in the tank ? the snails you show look like baby whelk or drupella snails. If so, they would eat zoa. Sun dial snails as well as Drupella, Heliacus and Coralliophila snails will eat zoas.

As far i as i know, nothing eats the sun dial (box snail). You will have to manually remove them. Also, sounds like they have had 6months to reproduce in your system. Ouch.

Where do you guys see sundial snails on those pictures? I see stomatellas and maybe colonista snails, maybe something else, but no sundials
Out of the pictures she posted, I don't even know if she has boxed snails.
the one I circled as red is the only one who could be a boxed snail - sun dial.
The blue circles are stomatella snails.
But it might even be a nicely patterned stomatella.
Maybe she's nuking her clean up crew.

The red circled one has a smooth shell, or at least no visible radial grooves, the checkered sundial snail has radial grooves that align with the pattern, like you can see on the picture that was posted of an actual sundial snail, and the pattern is very geometrical, not really random, they are also much flatter

I wasn't sure on the red circle, as photos can leave out a lot of detail. Hopefully she looked at the sun dial photo and didnt kill everyone who doesn't look like said picture.
