Or you could just buy Tiger Barbs wholesale...
I think that presentation is another key factor in fooling difficult eaters. If they eat only live feeders, then starve them for a couple days before throwing in one small live feeder. When they take it, follow up with another thrown in the exact same place and way. After a couple small feeders, maybe over a couple different feeding sessions like this, they are waiting for it and hit the live feeder as soon as it touches the water. Once they are at that stage, throw in a live one...and then, when they take it, immediately follow up with a dead one. Odds are they will hit it. From there, it's an easy progression to pellet-stuffed feeders, then feeder-scented pellets, and then just pellets.
The smaller the feeder, the better; smaller ones mean that more of them can be fed at each meal, so the training goes much more quickly.
And, as stated before...no other foods should be offered until the fish are completely comfortable with the pellets as an ongoing food source.
