Eggs! I've got eggs! At least I think that's what the male's up to. he's working hard, moving these little white spheres back up to his bubble nest. He took one blood worm from me, but otherwise couldn't be bothered. He was far too busy. I thought he was just an obsessive nest builder until I saw he scoop something up from a leaf and spit it out at the nest.
So now I'm waiting, fingers crossed, so see if I get some wigglers! I'm leaving the female in place for now since she's leaving him alone and it would be hard to get her out without causing a ruckus. I'll move her out eventually to control spawning.
