New male spit out 12 premature babies with pretty big yolk sacks 2 days ago. The sacks today are much smaller (pictures) and I started a BBS culture and will start a new one everyday. Pretty sure this is about day 18~19. Today they have pigment that is showing more and are starting to practice their upright swimming a bit. Anyone have input on when I can introduce BBS? Should I wait until yolk sack is all gone? Thanks
