hey dude, for my experience its not expensive to breed and to raise fry, but you'll need to have an extra time for them. for the set up, here is my set up.
*A 15 gal. water barrel cut in half or any large plastic containers will do
*A Styrofoam cup cut in half.
*some water plants
And thats it, my set up worth without a penny spending on it..just be resourceful.
For raising the frys, this is the time you spend some money for the frys food and more extra time monitoring them. follow this thread:
hope this will help you through out. GL!
