eggs? quick help!!

what are these....all over a plog and covering the bottom of a 4"x4" frag rack that the plug was on....saw my nassaris snail on it a week ago but thought nothing about it....although all 6 of them have had a few orgies.

certainly eggs, cant say for sure who they belong too...my nassarius snails usually left their eggs on the glass...i have always found that good guys leave their eggs out and about, and bad guys try to hide them..

But I don't have anything else in tank other than my fish, 6 nassarus snails, 1red leg hermit, and pods. I even did a thurough check multiple times day and night for the past two days and saw not even a sign of something....any other pests that leave them in a similar fassion as mine.
