Now it is time to purchase the fish! Buy hardy fish such as danios, barb, gouramis, and live bearers. They should be able to withstand the high nitrite levels and ammonia in the new aquarium. Only introduce about four fish at a time. Float the fish in the bag in the aquarium for about fifteen minutes before adding them to the tank. Invertebrates should be fed more frequently in smaller amounts than fish. Try to feed only an amount that can be consumed in the first thirty to sixty seconds. When setting up an invertebrate tank remember to include live rock, because some invertebrates feed on the parasites that grow on the live rock. Live plants are highly recommended in new aquariums as they will help to generate the good bacteria necessary to reduce the amount of ammonia in the tank. It is a good idea to test the ammonia and nitrite levels before adding fish to the aquarium. Begin by adding only three to four small fish. A general rule is to wait another thirty days before adding additional fish, because that is the incubation period for most fish illnesses.
