Infusoria in generally the early stages is mostly bacteria and small protozoans (15-35um) that may not be large enough foods for new fry. As the culture ages later stages of infusoria community are larger forms and could contain large protozoa and some rotifers, and maybe small crustaceans over the coarse of a few weeks?. I wouldn't be afraid to try the flake food paste with frequent water changes to keep water quality higher. Another option is investigate rotifer cultures added to infusoria or cultured by themselves. I checked on the web and there is a lot of good new information on infusoria as food for newly hatched fish fry since I worked with infusoria cultures back in 1972.
Try a couple different methods so you don't "have all eggs in one basket". All this is a lot of extra work for a few inexpensive FHM unless it is a learning curve thing.
