I'm looking to get my first gold fish aquarium and I've found a 66 gallon tank that I think should be enough volume for 2-3 comets, but I want to make sure the dimensions are adequate. It's 48.5"Lx12.75"Wx25"Tall. I'm wondering if the 12.75" width allows enough room for the fish to turn around easily once fully grown. I don't have a lot of room to get a tank much wider than that.
Also, would Fancy's be better for a tank this size since they are shorter, or would they be worse since they are less flexible and worse swimmers? Just want to make sure I get the right tank for the right fish? Any input is appreciate. Thanks!!
