ok so i left for a week at camp last week and while i was gone my dad was in charge of fish duties. well i told him to buy a dozen comets at petsmart to feed my needle fish and he buys some offbrand goldfish that is to large and kills both of my needlefish.
so i want to turn the tank into a convict breeding tank and i want to know how to sex the males from the females.
