I feed a mixture of Omega One and NLS along with supplemented frozen bloodworm treats and I am looking into feeding live BBS as occasional treats as well. If I am feeding NLS, my fish get 10-12 apiece. I have the small fish NLS formula, so the pellets are extremely small. I find that a couple of my fish that have issues with Omega One (presumably because they are larger) perked right up with NLS. I feel Omega One has slightly better nutrition, though, so I don't intend to give it up. When feeding Omega One, my fish get 5-6 pellets each. I really never see bloat because there isn't the same amount of icky fillers cheaper brands of food use.
