For those with experience raising fry...

i was unable to wean my last batch off and they eventually starved to death when the bbs didn't cut it anymore for nutrition and growth. I tried cylopeeze as well but to no avail. i heard they will eat cyclopeeze if you don't introduce bbs but never experienced it myself.
As far as cardinals eating pellets, they can learn to eat it but very difficult. I have a femal pajama right now that eats pellets but the male who's usually pregnant does not.
