Do you have any large tank yet? We can't give you advice based on what its going to be, we can only give you advice based on what you have.
Its going to be well filtered, how will you filter it?
Its going to have a lot of flow, how are you going to do it?
How are you going to maintain the temperature at 80?
How are you going to care for the fish while they're growing out?
How are you going to keep the jardini from killing his tankmates?
There's a LOT of questions you need to answer for us before we answer yours. You've already been caught in a lie with your "cousin" hacking your account (900 gallons, anyone?) and posting a bunch of questions identical in nature, syntax, content and tone to the ones you posted now, so you need to work very hard and be very careful what you say in order to reestablish your credibility.
EDIT: Nevermind the fact that you still haven't even provided proof that you even own a tank. With where you are in your interactions with this forum right now, I don't think asking for proof of basic knowledge of the hobby in the form of pictures of your current setup is too much for us to ask.
