Need info, Dovii female has laid eggs...

Congrats! I don't do anything differently when my pair spawns.
Just make sure the female has a hiding spot where the male can't reach her. I lost a female once after they spawned.

I have a pair about the same size as yours and when they spawn i don't do anything different same light schedual and feedings although the female won't eat but the male eats the same.It will take 3 or 4 days to hatch and a few more days til the fry are free swimming so about a week and moma will be escorting the fry around the tank it's pretty cool.My pair have been getting along well i do not fear the male killing her right now the pair are about 6" in a 125 gal with 4 red devil growouts acting as dithers for the pair so the male stays busy all day flaring up and postering at the devils it's fun to watch.

No don't stop your wc schedual i do a 50% change every week.

I suggest not changing a thing and the only time you need to get involved is if the aggresion gets to be too much for either one. My female was the more agg of the two when my pair spawned. The first time none of the eggs hatched but the second time they took. If any of the eggs turn white they are infertile. Good luck on the fry man.
