You can say I never condition them. I always feed them either live (ML, daphnia, ant eggs, fruit fly, small earth worms .... what ever is available), frozen BW (most of the time), chopped shrimps, tubifex (when food source is scarce or when I'm too busy). I feed males until they begin to bloat. I feed females all they would eat.
WC 30 - 50% daily and 100% weekly in 1g tanks. Top off only in solitaries (females) and breeding tub (male).
I don't look for nests nor breeding bars. I only make sure that the male is active and healthy, show him the female, if they flirt then I release. If they don't I exercise my male then rest and reintroduce the next day (almost never). If the female is reluctant, I place her in a solitary for a few days then reintroduce.
