I think 80 gallon is a minimum, true, but the length of the tank is important too. My tank will give the fish less than 4 feet length because I have a lot of width, 5 feet is required for natural behavior. Plus, I don't like to keep to the minimum. Just a personal preference, as I'm convinced it will be to the benefit of the fish.PoopSmart;1493736; said:What kind of tropheus? I don't think a 95 would be bad for a tropheus duboisi community.
