I bought a big bag of it at a fish auction. Don't know the make, no name on the bag, but I have fed it to my Tibee and CRS babies from birth and all are growing extremely well...didn't lose any of them. Great stuff.
I mix it with water from the tank, then squirt it in with a tiny syringe, not a lot at a time. I sometimes add gravidas to the mix and mix it well then squirt that in. Female berried shrimps like it too.
