Thanks! That's what I'm finding as well. Though interesting that I see it mentioned with the flamboyants and not any of the other cuttlefish- at least in what I've read. I've also been wondering what my current cuttlefish are but can't tell a thing. They are all about the same size so either all same gender or size doesn't work with the dwarf species.
I'm still waiting to see if my two dwarf cuttlefish will lay eggs or not. I have seen from time to time what looks quite similar to breeding. The two have often given their face to face hug before breaking up. The two are also always close together.
But will see!
