Angel egging/laying substrate options

  • We are currently upgrading MFK. thanks! -neo
Parents seem diligent but there's another pair of angels in that tank, along with a 3~4 small swordtails (and a 6" silver arowana... long story).

So, when do I move the tile to the greenwater/live-food system?
Now? At eyes? At wriggling hatch?

Or do I leave them with mum&dad through detachment? If so, when do I net them to greenwater? Free-swimming competence?
IE: When will dad stop protecting them and/or start eating them?
