when u hatch brine shrimps and they are gonna die soon could you freeze them into little cubes and use them?? or when they are dead cud i jus freeze them up??
Yes you can, I've done it before. It works great for fry that need to be fed a couple times daily when you go on vacation. It's also a great backup for unexpected fry, or if something goes wrong with your hatchery.
I freeze them as fresh as possible, right out of the hatchery, rinsed, then frozen.
