Hi Mike Maybe I've been lucky or something but I've never had a problem with my apistos feeding them blackworms and I've been doing it for the last 3 or 4 years. Maybe the fact that I only feed blackworms twice a week and only a few worms at a time might account for me having no problems yet. I use other foods as my live food for morning feedings. I do a very good job rinsing my black worms every day so that a 1lb bag of black worms feeds all my killies, livebearers, corys and apistos for 1 month. I run about 80 tanks and only feed a few times each week. I need to make them last the month for my killies. I guess it's been my good fortune, but I do find them a good conditioning food and a few of my friends who also raise apistos and west africans use them even more than I do.
