Keith, it occurred to me that the Foodsource "mealworms" might have an adverse effect on your fish. After all, they were designed to be "fed" to fish that don't normally survive. One of the baits I had tested yesterday was still in the cup of water I had put it in. It had almost doubled in size, but it was still very firm. I have doubts that they will break down in your fishes bellies, and that could be a huge problem for them.
I sure hope our experiment doesn't result in the loss of your fish!
I wonder if some type of laxative food would help. IIRC earthworms have that effect. Before I do any more damage I should say that I don't actually know if a laxative would help or hurt the situation.
