I have decided to switch from munba to peacocks in my 75 gal tank. I'm planning on ordering from one of the sponser's on CF. The sponser suggest 25-30 fish at 1.5 to 2.0 inch fish for a 75 gallon tank. My question is this is this a high number of fish for a 75 gal tank? Will this high number cause some of the males not to color up once they reach maturity? Any advice is welcomed and appreciated.
