Goldies are fine, and fairly simple, as long as you consider their needs. Figure 3-4 times the water you would for the same size tropical, stay away from the ones that have been bred to extremes (bubble eye, celestial, telescope). For first time goldfish owners, I would stay with either the comet or shubunkins as they are the easiest to start with, or with some of the more common fancies such as the fantail, pearlscale, black moor, oranda, ryukin, or veiltail.
