id pls

does anyone know what these are? i know they are eggs but from what or should i say who?
it is located under my spongodes montipora, they are connect to vine or a stem like string. when i first moved it,it was swaying in the current so i know or have a feeling that they are not Nude eggs but i could still be wrong. the pic was taking with 1x zoom
the only possible pairs in my tank are cleaner( ruled out we all know why) and two cardinals ( ruled out also, we know why).any ideas?:-/

thanks allx

 

Look like nudibranch eggs to me...

 

Yeah i just saw something similar inside of a vortech that was identified as nudi eggs.

 

okay, getting them out now

 

you guys called it. when i scrap it off the bottom of the mont into a small container it started to move. it was a big nudi with the eggs attach to the ends of it. i have a lot of crazy gluing to do tomorrow.

 

did you get more pics to show the nudi

 

as requested...
