I purchased an aquarium about a month ago (a 30 gallon). The person at the pet store told me that goldfish would help the tank fully cycle before adding any other fish. My initial intention was to keep tropical fish. I called the fish store that I purchased the goldfish at to see if they would take them back and they said no. I am now left with 4 fantail goldfish (they look like orandas) and one small lionhead goldfish that need a good home. I purchased the fish for 7 dollars each (I still have the receipts) but I am now offering them for 4 dollars each. They are medium in size and more then anything I really hope that they can find a nice happy pond in someones home. Please contact me.
