Hi Wuvmybetta (wuv that name!). I feed him dried b/w. I used to buy frozen but I just have the one betta and didn't like the idea of keeping them for such a long time, even if they are frozen. I read that you have to be really careful when buying frozen b/w, because there's a risk of bacteria/parasites in them, which made sense to me, because first of all they're frozen (assuming they are not ever thawed out accidentally, or during transport, etc.), then we bring them home, break off a piece, thaw them out, which means they sit out while thawing. Bottom line is, my betta got pretty sick and I figured it was from the frozen b/w and so I switched to the dried and he gets them as a treat once in awhile. I had been feeding him the dried too often, because he got really lethargic and swollen, now he looks awesome, slim and is very very energetic. I never read anything negative about the dried b/w. Do you remember where did you found that info?
