got lucky,
i noticed the female attacking and biting the anemones tentacles by a piece of rock they had been cleaning for the last 24hrs
the anemone retracted on that side then the maroons started spawning
the female laid a couple of tracks of eggs
then the male passed over them
while one was at the eggs the other was pushing the anemones tentacles away
they should all hatch as the last lot did but had too many other things to do
have phyto plankton and rotifers brewing now though
