Feeding

[NickeyV]

I was thinking of buying some worms or nightcrawlers and maybe breed them. Does anyone else do that? The past couple of days Lucifer lost interest in eating fish and won't eat it. Then yesterday found a worm and showed her it and she wanted it. I didn't feed it to her cause I don't know what kind it is and it doesn't look like the type of worm you always see in your backyard. Anyway what are the type of worms that they can and cannot eat? I tried looking on the internet to identify it but can't. Maybe you know what it is. In the pic the closest it looks like is the worm in the bottom left corner.
