I work in a lab that studies larval fish nutrition and am not aware of anyone having really good
success raising marine fish larvae on non-live foods. We use enriched BBS and rotifers pretty much
exclusively until the larvae metamorphose and will take dry crumbles. Finding a suitable non-live
feed for larval marine fish has been a sort of *Holy Grail* of the aquaculture industry, but the
larvae are sight feeders and don't seem to recognize non-moving particles as food. This feed
described above is probably designed for use after a couple of weeks of rotifers or BBS.
As far as killies go, you may get some fry to feed on particulate feeds after a couple of weeks
start on BBS, but you will probably suffer bigger losses of fry (and lower growth rates) than if
you stuck to live foods. It's worth a try if you have large numbers of fry to play with, but I
personally would'nt use it on rare species or fast growning annuals.
