Gravid-holding eggs

My littlest maroon was caught nipping at my elgance coral the other evening? Is this a sign? The pair host to a small BTA and a large carpet. the smaller is 3" and jet black and the larger is bright orange/red and about 5 1/2". They have cleared away a huge nest under some rock work, not exactly near the anemones. The other night I saw a huge sheet of about 2,000 clear/white eggs along the glass of the tank, figured it was just snails...
