For those in North America, the best prices on earthworm sticks are fromhttp://www.kensfish.com
I use them as the staple diet of all my plecos and Discus. Other foods I use are frozen blood worms, Tetra Color Granules and live black worms,
Discus sometimes take a little while to get used to new foods but I have found that both wild and Domestic Discus eat it very well once they become used to it. The plecos I keep in with my Discus get right out there and grab their fair share.
Earthworm sticks are the primary food for all my pleco fry.
I received 10 pounds of earth worm sticks last week.
Have you considered wearing latex surgical gloves and placing frozen blood worms in a container of water from which you can suck up however much a tank needs using a baster dedicated to fish use?
I have heard of others becoming sensitive to blood worms.
How strong an allergic reaction can be can range from merely annoying to life threatening
I used to harvest real Tubifex worms and sold 10's of pounds every week at wholesale to shops throughout the PNW USA back when I owned a fish shop.
I became allergic to any dying or broken worms and the water they were in. It was so bad that once I dropped a container and the contents splashed back on my arms and face. I developed a strong Hives reaction wherever that material touched my bare skin. Not long after, due to the Clean Water Act, the cattle feed lot up stream closed down and the stream was channelized which put an end to my free Tubifex farm. Interesting to me is that I haven't developed cross allergic reaction to California Black Worms. CBW belong to a different genus and require cleaner water to thrive than real Tubifex. They are quite different from Tubifex. When I did have an unlimited supply of Tubifex I had some rare breeding experiences. Once, a tank set up with Kulii Loaches in peat moss produced a bunch of little Kuhlii Loaches.
Anyway, I would find an allergy to frozen blood worms a big problem since next to the 20 pounds of earth worm sticks I use annually, frozen blood worms are the next in volume of the foods I use. I use 10 oz.s of frozen blood worms every day. I buy about 100 pounds a year split between two orders of 50 pounds a year which I partially share with a fish friend. We try to use all frozen foods within 6 months.
For some reason, my fish do not seem to care for frozen brine Shrimp or Mysis.
Which is fine with me because I don't think frozen brine Shrimp are all that great of a food.
