Doing frequent water changes is going to keep your water in good condition for your fish. I wouldn't worry about Liquifry. Flakes will be fine. It's not as high in fat and protein content, so your fry may not grow as fast as on flakes, but that's not really a concern. Crushed up flakes are good. I'd say after a couple weeks they can handle almost full sized flakes. They may have to absorb a bit of water to soften up, but they will do fine. Good luck.
