freeze-dried blood worms and freeze-dried brine shrimp? I tried presoaking the blood worms but they won't sink, and the fish won't go for anything floating up top for some reason. The brine shrimp come in these little blocks. Do I break them apart and soak them too?

After you soak them, try pinching them gently to squeeze out the air. I would the same with the brine shrimp. The food should then sink slowly for your fish to eat.

Thanks, I'll give that a try.

Where can you get this kind of food from?
