best of luck feeding the fry! just dont over do it and make sure you do not feed any shells!
-oldfishlady is right aquarium salt is expensive...i was lucky to get a lot of non-iodized salt from supermarket for i think$5 for a big box. so i use that =]
-i start making bbs the morning day two of free swimming and by next day they'll be fine i dont worry too much because if they DID free swim a few hrs earlier i have Microworms and vinegar eels to sustain them a bit before bbs but so far no problems
-i use a topfin fine net i find coffee filter takes a bit longer for me but w.e works =]! just remember rinse!
