Does anyone know a good internet resource for goldfish care, more specifically common goldfish care? My boyfriend has a grey, possibly, goldfish living in a betta bowl on his desk at work. He didn't buy it, someone brought them in for everyone, and his is the only one alive, and it's a trooper. I'm going to have him snap a picture Monday, and maybe one of you well-educated people can confirm that it's a goldfish. He has no idea. I know no matter what it is, it doesn't belong where it is, and from what I'm reading on them, 10 gallons is a bare minimum for 1 goldfish, and they usually like company, but I want to get the goods. One site was demanding a 55 gallon for 2 goldfish, which is way outside what I could manage for the little guy, but anyway... resources would be great.
