I am converting my 375 gallon tank to a hap/peacock tank if I can make it work. Tank is 96x30x30 and will be mostly open with a few low rocks in the sand. Should I just start with like 5 of a bunch of different things and see how they grow out with some males and females? Would be hard to fill it with all males buying them bigger once they can be sexed. Would that be a big enough tank to have males and females in a big mix like that? Should I just draw down to like 10 different big haps and put 1 of each in and let them get 10-16"?
