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 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.
