Koi Forum • feeding dried mealworms : Koi Talk

Read somewhere here about feeding dried mealworms. Bought a tiny container from garden centre, Koi loved them. I thought they were a bit sharp, should I have soaked them, sounds silly I know, don’t want my fish hurting themselves.
Would like to buy in a larger quantity and hopefully that way they will work out cheaper, anybody know where I could get them.
