For those new to breeding egg layers which have very small fry, like Rams, this might be of interest. I see quite a few people going to a lot of trouble getting infusoria cultures going. I find you can save yourself a lot of aggravation by using small diameter prepared food. This is nothing new to experienced fish breeders but for newbies this might be something of interest. I have numerous Ram free swimming larvae and wanted an easier way. I decided to try Golden Pearls Fry & Coral Fish Food 'Size 1' 5-50 micron. It works very well even for the smallest of fry and a heck of a lot easier. Its made in a variety of sizes. Hope this helps somebody.
