I think you'll find a 75 gallon is to small for those fish at adult size with dither fish. you need a 6ft or longer tank for some dithers. When introducing new fish you intro the less aggressive first and the most aggressive last. If this mean catching your current guys and putting them in a bucket with an air stone for an hour while the new guys get used to the digs you gotta do it.
I did do that when I first setup the tank. The first fish in the tank were 20 Rosey Reds. Had them in there a month or so before putting anything else in. All was fine for a few months, then they all started to disappear.
I don't think an hour in a bucket will do much good. When I put the new dithers in, they are fine for the first 6-8 hours or so, but when morning comes they are all dead.
