Wow, I would've thought those fish, at least the cat and bass, would be all over worms. I better make sure my fish are into them :/ Have you tried drying them out? Sounds like it could be a pita, but it was brought up earlier.Nice, my worm bin is going strong as well.
I dont use it to feed as much since I only have 4 fish (cichla, gulper cat, and 2 rays) and all 4 ignore the worms. I mainly have it to make vermicompost for my veggie garden and if I eventually get a fish that likes worms, i have an unlimited supply of food for that fish.
