Not only is live blackworm rich in protein and nutrients, but they can survive for an indefinite periods of time in a freshwater tank. This which means that unlike other foods, they will never foul the water and will live until eaten by your fish.
They turned up on time alive and happy I think. All wiggly and ready for their new home in a taro plant. I take a torch out at night and watch them come out to feed on what's in the water column. Thanks guys
