Can I keep a goldfish in a six gallon tank?
I'm thinking of getting back into the fish keeping game. I used to keep Bettas. They kept dying and I gave up. I now find that I miss fish. So I thought I would try goldfish again. I used to keep them as a child. Back then we used to kep them in small bowls. They managed to survive so I wondered if it would be alright to keep goldfish(just one) in a six gallon tank?
Do goldfish need company or can they survive on their own? Also do they need a heater? Can I use aquarium salt in the water?
Any tips you all can provide will be appreciated.
