Feed microworms and VE for the first week and then add in BBS the second week. Feed all three for the first 3-4 weeks and then switch to BBS alone until week 6 or so. Then add in crushed dry foods.
Don't hatch too much BBS or you might end up with nasty tanks as it only lives in fresh water for about 24 hours.
All this varies on tank size and cleaning. I'm using my experience in 4 - 10 gallon spawn tubs and 30 gallon grow out tanks with every other day 50% water changes.
This. From experience. On my first spawn I did BBS for the first 4 weeks and found my methods of removing the cysts was very poor.. they caused some minor SB problems. I've since picked up proper filters for removing the cysts. A mix seems to work better, my 2nd and 3rd spawns where raised on a mix and I've had no problems with swim bladder at all.
Also, Micro/banana/vinegar worms are a LOT easier to take care of and prepare.
