The live black worms need a daily water change with water the same temperature as the culture. It is 1 more thing to do each day to keep them alive & they don't sell for much money. They also only live for a few minutes in salt water. If it was going in a fresh water tank they would survive until eaten.
They are vendors which sell them. If we convince Carlos to buy bulk that would be awesome!
Why not just buy them at the Pet Shop?
