I have bought in 3 new discus each of 1.5 inch in size. At the store they were given tubifex, and I find that they are addicted to it. They will not have any other food except tubifex. I have not goven them tubifex for last 5 days and they still refuse to take any food.

If I give tubifex they eat like "pigs".

I make the beef-heart mix and also have tried frozen bloodworms, and they have refused all.

Regards
