Don't immediately take out the fry. I don't think you should ever do that if the parents are taking care of them. Leave them with the parents as long as you can. When they get about an inch or so, then sell them. Unless your LFS knows about Festae, I wouldn't try to sell the fry to them. You could get cheated out of profit for a very sought after cichlid. Try to sell as many as you can to knowledgable LFS or individuals that really know what you have.
