My bass are young and mostly prefer live feeders. I keep night crawlers in my mini fridge if I can't get to the pet store. . . Sometimes they take it sometime they don't. I assume you keep your nightcrawlers refrigerated, as do I, and I dont think the bass like them cold. I always take a worm out, and put it in warm water ( a scoop from the tank ) and swirl it around to rinse it off and warm it up. After a few minutes of letting it sit, I cut it into smaller pieces ( I have 3 bass, all about 4 inches ) and they mash it. One of mine is more aggressive and will eat whatever, but the other two are picky, especially the luke. But like everyone else is sayin, you got a problem we all wish you had.
