Around 7 to 11 inches. I feel a 50 gal would be nice wit adequate filtration. Not being an expert in goldfish matter though, thats just through general knowledge and experience. 30 might be enough according to most websites.
Thank you Fishfanatic!
Finally, some tangible numbers I can work with. Knowing that these fish can grow to that length (under ideal conditions), looks like we're headed to a minimum 75 gallon capacity tank. Maybe even a 100 gallon assuming that in the near future I can swing the logistics of that aquarium (room to put it, money to outfit & run it).
