During this cold weather, when we get livefood delivered it may appear dead. But they are usually ok and just hibernating.
To revive them,
Unpack the outer boxes immediatley
Carefully lay out all pre-packs so that air can circulate around them
Place the pre-packs in a warm dry room (15-25 degrees centigrade)
DO NOT UNDER ANY CIRCUMSTANCES APPLY EXTERNAL HEAT TO COLD LIVEFOODS. For example do not put them on heat pads/strips,
