if you have a place where you can purchase live blackworms/bloodworms...my method works...well, it worked for my anyway...and it was pretty easy.
Okay...this is what worked for me...hope it does for you as well. Buy live blackworms from your lfs and consistently feed them every 12 hrs for about 2-3 weeks, and feed them feeders 2-3 times a week. After 2-3 weeks of feeding them live blackworms, i got a little tupperware container and started with 1/2 cube of frozen bloodworms and added water to melt the ice. After all the ice was melted i would put live blackworms in the container as well, then i would pour some into a net ndd feed them and they would just gobble everything, live blackworms and frozen bloodworm and all. Do that for about a week. Now i just throw 2 whole cubes in the tank and they devour it while it melts, no problem.. Now im mixing frozen plankton with the frozen bloodworms, they still occasionally spit some out here and there, but getting use to it.
