im looking to stock my new tank and would really like to keep 2 oscars and at least 2 electric bllue jack dempseys. other fish of interest to me are choclates ,convicts and severuems. how many fish of this size would be good to keep with out over stocking my new tank. i have kept these fish in the past but only in species tanks in very small numbers. this is my first tank over 55 gallons
