M. Tournesol Posted Tuesday at 10:14 AM Hi, This morning, I discovered two eggs sack on the glass of my tank. I am asking myself what is the creature that produced these eggs. The eggs seem to be suspended in some sort of gel. My tank has for unique habitant 3 cerith snail wish have already produced different locking eggs. My aquarium was also stared with 100% live rock. Could this be the eggs of a kind of flatworm? pictures 1 and 2 are of the same eggs sack. Quote Share this post Link to post
