I have to agree with all above statements. I have been breeding fish for 20 years and its really hard to do for a profit. The only times I have made a real profit is when a new fish is introduced to the hobby and I order them in directly from Africa. Discus are great sellers but breeding is problematic and to some a real challenge. Its also amazing how much time and money is spent raising your fish to a salable size. Good Luck, but do it just for fun, and if you make money, great.
