I got some new food (I've never tried out before) for my betta fish. It's Hikari freeze-dried brine shrimp. I'm not sure how use use it, because it's like this tightly packed brine shrimp in the shape of a rectangle-cube about the size of a quarter, I'm not sure how to use it. I tried to cut it into smaller pieces, but it just crumbled into a mess.

I have checked the container and the website, but i can't find any help. Maybe I'm just supposed to give it the whole thing

If you know anything about this, than please help. THANKS!
