Hello, I hope someone can help.
I have attached a picture of what looks like small black eggs. They were not there yesterday and appeared over night. My tank is a marine nano (20 gallons) and only been set up a couple of months. I have 1 blue cheeked goby, 2 peculiar clowns, 2 hermit crabs and a dancer shrimp. I also have 2 small pieces of live rock.
Does anyone know what they are?
