Hey my goldfish died (it was 15 years old!! Sharkie the Immortal we called it) and we have all this awesome stuff lying around now. We're asking $100 for everything OBO as the tank itself was almost $200 (and is like new now; fully cleaned etc), comes with fake plants, bottom fillers (pebbles), filters, light, stuff you put in the tap water for it to be good for fish, goldfish food, net, box, etc etc etc. Basically everything you could possibly need for a freshwater fish. I don't have a heater or anything for it but I'd bet you can work something out for it if you want tropical.
