I suggest keeping just 1 male to 1 female. 2 female to 1 male is always better though.
I feed my Scarlets crushed flake food
and they all accept it willingly. Though my Badis are F4 and F5+ generation so they've always had crushed flake food to begin with so it's a norm for them.
For LIVE Food
I treat them to micro worms, scuds, daphinia, black worms, and glass worms
. Feeding a lot of live food always get them to breed for me.
They breed like bettas so expect a ton of fry.
There's really no trick to keeping these guys.
~ Good Luck
