Agreed,that's why I never bothered. In a panic I set up the bbs hatchery this morning. The bbs hatched a few hours ago and I saw a few babes eat. I had to keep moving the night light around the tank so the bbs would move from cluster to cluster of fry 

After feeding them bbs the first time,the next day the hunter in them was born and they're just precious with their 'strike and devour' 

My bad.
better luck next time

So, I'll wait and see.
