Some are black and some are clear, hopefully this is a better picture.
Not sure if the Molly and damsels would breed together, but I only have the one Molly in my saltwater tank.
There mollies, I had a similar experience in my freshwater tank. I bought 2 and the male died off then a week later or so the mother have birth.
Did you recently get the Molly?
No, I've had the Molly for about 2 months now. How long are they pregnant? This is saltwater, it's the only Molly in my saltwater, I don't understand who would breed with her?
Definitely mollies. Female mollies are able to store sperm from multiple matings, so you may well get additional broods even though a male isn't currently present.
