Any hope of persuading a CBB to take non-mysis foods?

So basically so far nobody's saying that they had one that would take flakes or pellets ... I'll take that as a "don't even bother trying" perhaps.

Never say never. From page 2 of the following thread:

When I fed the rest of the tank NLS pellets........ He started eating the pellets like they where crack!

Obviously not an easy species to convert to pellet foods, but at least in some cases it can be done.
