I'm going to take a guess that it will go bad unless eaten within a day or so... I'm going to try frozen ones and just thaw them in tank water a few mintues before and see how that goes.
I just break off pieces of frozen bloodworms and drop it into a cup with aquarium water in it. After it thaws I drain off most of the water and add more clean to rinse them off before feeding them.
yea when i first stared using frozen foods i was carful to use aquarium water and unthaw it a bit and blah blah blah but now i just toss the frozen chunks in and they eat it just the same
