Correct/comfortable Tank Size?

[bio-tech1]

hey y'all. So i have a fancy twin tail gold fish. Had it for a few months. When i got him it was very small so i put it in a tub i already had that was cycled because i had perviously used it as a breeder tank. It is a plastic storage tote. It is very short and long, made to hold shoes. Around 17-20 gallons, not completely sure. Anyway, i am thinking that maybe i should move him as he is always hiding which i think may be a sign he is unhappy. Do goldfish prefer more of a box shape, like equal length, width, and depth? Or do they prefer a long tank? I just want whats best for my goldfish.

I would keep a fancy goldfish in a 29 gallon personally, I think a 20 is too small.
They don't usually prefer the shape of the tank, but 29 gallons are higher, they have good dimension.

Goldfish do better with a tank that is longer than tall. A 40 gallon breeder would be a great size for a couple of fancy goldfish.

I also must mention that the best goldfish keepers I know are @Galathiel and @Goldiemom

I agree that the length is more important. Goldfish like to explore the entire tank. I just bought. A 20G long for my baby goldfish . They enjoy the horizontal room more than depth although they swim at all levels. A 40 G would keep them happy for life. Get him another fancy to play with too if you can.

Having decor in the tank or tub would be helpful too - it can make him feel less stressed. I would also move him to a larger tank so you can get him a friend - goldies do well with a goldie tankmate.

ok what makes for good decor with a goldie? I currently have a half coconut hide that is made for hermit crabs in as well as some big fake plants with big fake leaves that cover the back of the tub.

Plants and large decor they can hide behind are good!
