I've not seen it listed in a while. The company is still in business, as far as I know.
Liquifry was fine flake in a suspension with a preservative. You can make your own, every day as it will rot, by mixing finely crushed flake food in a bit of water and letting it sit for a bit so the food will moisten.
For fry I use Hikari First Bites, Golden Pearls, Ken's Fish #00 Growth meal and fine Cyclops Eeze.
