This is just my opinion. Take it for what it's worth. I can't count the number of times that I've had people write or call me with a problem with a sick apisto. Many times it's a fish they have had for month that suddenly pales out and stops eating or develops red sores on the flanks. 3 times out of 4 they mention that they feed black worms to their fish as a live food. Black worms are a tubificid worm and just like red tubifex worms require a septic environment for feeding and breeding - just not quite as bad. No matter how well you rinse them there is still the chance of introducing parasites and disease organisms with them. Anything that would completely sterilize the worms will also kill them. There are so many other great live foods out there that can replace black worms. I'd recommend red African worms or baby earthworms.
