Sandybottom, where do you think she will get the insuforia she will feed with a lettuce leave? Did you just make this up?
LIVE food. Not frozen. Swimming, alive, bouncing around food. If it is not moving you can foul your water with egg yolk all day and your fry will starve to death watching it sink to the bottom of the tank.
The good news is you can hatch BBS (baby brine shrimp) at home. Its simple, cheap and labor intensive...So make sure you want to make the commitment. egg laying fish fry are not the same as livebearers like guppies and platties- the babies are teeny tiny and their instict, their teeny tiny fry brains smaller than a grain of sand, tell them to eat anythign that moves- If its not moving they wont try to eat it and they will die.
