Are blackworms safe for rays?

What setup do you have? I was thinking about doing it in a 10G w/ a sponge filter. Thanks!

I use cut up filter inserts and scrubbing pads (soap free of course) as the growing media and feed them a plant based pellet fish food. Other than that, its a rubbermaid container with a sponge filter. I got all my info from Culturing Live Foods by Michael Hellwig.

Ive been starting my pups on black worms only because they stay alive in the tank so when there ready to eat its there. Then i switch them to red worms when they start eatting really good.
