My cherry shrimp molted and left its (fertilized) eggs with the old shell. I'm assuming the eggs are fertilized because I can see little eyes. Is this common? Or is something wrong with the tank?
Uh.. This is not common at all. I would take the molted shell and the eggs - be careful and put them into a net and hang it in the tank so they get tank water as well. Make sure you put it somewhere where nothing can get to it - ie. snails. They will eat the eggs.
