BBS is too small for adults.. are you meaning adult brine shrimp? And are these frozen or freeze dried? Freeze dried are poor food to feed in general, and not ideal to feed when conditioning.. at least not as the sole food.
Heater should be set at 82-84.. don't want less than 80 (ideally) in the spawn/grow out tanks - need lots of warmth.
Keep filter off or on very very low during spawning.. can ruin nests and push fry around at first.
Don't forget during conditioning to keep the male/female from seeing each other - only allow them to see one another for 5-15 minutes a day.
Are you in a dorm or at a house? In a dorm it will be near impossible to breed these fish and raise the fry..
Nothing wrong with VTs..
