HI Glenn,
Thanks for the feedback and positive comments on the forum! Glad the Fish love the worms!
The current batch I have in house for the pellets is good to until Jan 2016, but in I'd guess much longer. I am almost out of that stock and have a new order coming . I think if the fish are taking to the Blackworms well, you can try the pellets now., you'll do best to let them eat those exclusively a few days, as it may take them time to get used to it. I have had many say there fish took right to them though. AS for an amount to feed, I'd start with a pinch,its subjective I know. but its best to feed them too little , than too much. If they eat it all in few minutes and are begging for more, try another pinch.
Best always,
Al
