I'm not being mean, but if you aren't able to afford the proper equipment, etc, to properly care for fish, maybe now is not the time for you to do this. I admit, I made the same mistake myself when I started. Thought all I needed was a 15 gal tank kit and FOUR (dear god, the things I've learned!) goldfish. LOL! Found out with time, research and the unfortunate deaths of my fish, that it really does take some money to do this right. Otherwise, all you end up doing is torturing the fish unfortunately.
