Jean;84582 said:If they're fertile they'll develop eye spots and you'll be able to see the squirts changing colour. The darkening you mention...........if it's a kind of all over brownish...it's algae. The female octopus normally blows sea water over the eggs and brushes them gently with her arms to prevent algae forming and to keep the eggs oxygenated. If vigette is not in the tank then you need to take over this job, we use a turkey baster and gently squirt water over the eggs every so often.......but Mum will do a better job!
They're so small I don't know if I could see eyes at all. They do appear to be a bit brownish. Moms in the tank with them so I'm hoping she's taking care of them.
