Another easy way to harvest grindal worm without
dirt is to feed a piece of sandwich bread instead of baby cereal. Teresa
taught me this trick and it works well. You don't even have to bother with
plexiglass. Grindal worms swarm around the piece of bread in such
abundance that you can just pick off pure worms with the tip of a plastic knife
or a popsicle stick. Another benefit of this (at least to me) is the mold
inhibiting quality of cheap sandwich bread. (I don't know what they add
to retard molding but it seems to be safe for fish.) I
tend to overfeed with baby cereal and used to get the bedding moldy and spoil
the bedding and the culture in no time. Grindal worms have voracious
appetite and devour the small chunks of sandwich bread in a day. If you
are worried about nutritional balance of the worms, I suppose you can feed the
worms with a small amount of quality fish food.
