They will not harm them; however they will not live on the food scrapes you are putting in your farm like the red worms will.
Feather duster worms live in the water. They need a strong enough water current to bring in food, so they like to live in the ocean.
Worms can live in a container for several weeks to a few months, depending on factors like food availability, moisture levels, and temperature.
There are worms that are parcites and live of from other animals like tapeworm and ring worm and there are worms that live in soil like earthworms.
worms
newts will probaly eat the food since they'll eat anything that looks like food however i don't think its good for them i use frozen blood worms and live meal worms for mine
you feed them, maybe live fish, turtle and teripin pelets/food. They also like live blood worms.
because they want to live
They either live on (eat) the animal they are in, or live on the food that the animal eats.
well, that is a tricky question, but i believe they live in the ground like most worms
Yes they do but they like live worms better then dried. They also eat meal worms sometimes.
If they are dead and decomposed, yes.If you piut in live ants, they may attack your worms.
