So I am thinking of setting my tank up with 2 rocket gar, Redtailed barracuda, silver dollars, a rare fw barrracuda none like any I have ever seen no pics but its at my lfs and its no were on the internet and last some payara. Will all of these fish be able to work with eachother by any chance? Also does anyone know where to get scombs at 2 inch for a good price?
