Are these fish you already own or are planning to get? The problem with buying fish that donít fit your current tank is that many people plan on upgrading down the line when needed but something comes up that makes that difficult. Personally I think itís better not to put fish in tanks that cannot support them as adults.
That said ... Probably, but goldfish get huge fast in good conditions and are extremely messy. Iíd keep a close eye on your nitrates as they get bigger.
