It would depend largely on how many fish,what particular fish,and how large of a tank. Personally ,,I wouldn't do it. Why make things more difficult? (ie) water changes ,and daily testing. The bacteria develops in proportion to the amount of food available (fish waste,fish poop,fish food.) By adding all of the fish at once ,,the bacteria will need time to develop. In the mean time,, Ammonia levels could become uncomfortable to lethal overnight. If you have healthy fish in your other tanks, best to add them SLOWLY to the new tank. Filter material,gravel (in stockings), and decorations from the smaller tanks will all help seed the new tank with the needed bacteria. Were it me,, (and it ain't) I would perhaps add the fish ,,depending on size,, one or two per week (7 days).
