Yes they did take turns fanning and they fan every now and then but they let the current do most that work. They placed the eggs quite well this time.
As far as parenting skills, they attack and attack hard, thursday I did a PWC
on it(again today) and thats when I noticed the eggs after being brutally attacked by the mom moreso then the dad he stuck by the eggs flaring everything he could at me.
There are two other breeding angels in there(3yo), pair of breeding curviceps,breeding pair of gbr's, 4 dwarf plecos,kuhlli's oto's corydoras and they are keeping them all well away from the brood. Nothing injuring but they are being very protective parents. 3 years in the making and finally success. On the other hand KAI's pinoy female and one of my super veil blue marble males have their 3rd set of eggs on lowryders shale and are as well being very protective unlike their prior spawns.
I think a pair of my dad's discus are spawning right now too, I know my corydoras spawned the day before yesterday and there are fertile eggs in the chaos of their spawn. I think the high pressure moving in set them off, temps dropped almost 30 degrees overnight and then it all started.....
