Probably not. Goldfish are very messy feeders and can get very large (up to 14") You would need at least a 4-5 foot tank for a pair and adequate filtration. Unfortunately the trend is to keep them in completeley inadequate conditions because they can "survive", however, they are unlikely to thrive, often having their growth stunted and lives shortened. An unfortunate end for such a beautiful and long lived fish.
