Let me give you some free advice, if you want to succeed in business,, you need to get off your arse and do the work yourself.
Here's an example,,, go out there on the web,,,, cruise the many many forums and BB's that deal with franchising. OK,, now find someone who has a McDonalds franchise,,, now,,, ask them how much money it cost them to start-up,, and how much money they make every year
I guarantee you won't get an honest answer,, or any answer at all. A McDonalds owner in Alaska would not PI5S on a potential McDonalds franchisee in Alabama,,, even if he was on fire.
If you're going into this to make money,,, as a business,,, you're on your own,,, why should anyone here help a potential competitor? (Don't waste your flames,,,I'm only saying what a lot of folk are thinking).
If you want to find out how much you can get for your fish,, breed them,,, raise them to market-size,,,, then try and sell them where you live,, that is the only way that YOU can know what YOU can get for YOUR Black Ocellaris. Asking folk here is a waste of time.
So first,, let's see you raise 2000 Ocellaris a month. Then keep them for 4 or so months in an appropriate grow-out system (let's say 10 fish per gallon,, more for Maroons) ,, so you're looking at 800+ gallons of grow out space,,, plus filtration,,, plus food,,,, plus electricity,,,, plus your time. Costly,, costly,, but that is where you need to go.
This is where you are right now: you can't even justify a 10g QT tank and your siblings are dumping their loose change (and god knows what else) in your tanks.
