i keep my rag in a tray with a splash of water either covered with damp news paper or sea weed, lug keeped in a tray with the bottom just covered in water ( sea ). best to check daily in case any do die or burst, keep spare water in the same place as the worms as a sudden change can cause lug to burst. hope this helps you out .
sorry i ve been off the board but i put a new program on my pc and i couldnt get back to nesa. took till now to get it right and i dont know how ive done it. by the way white rag is the same as lug for storing but it should be cool but not to cold.. it you cant keep them give them to me i will find them a good home,,,,,,MINE.
