After doing some research and averages, I've found that I can safely assume that these are the following maximum lengths for the listed Goldfish
*rounded up to the nearest tenth*:
Bubble-Eye/Celestial Eye- 4.3 inches.
Black Moor- 6.2 inches.
Oranda- 9.5 inches.
Ranchu/Lionhead- 3.5 inches.
Pearlscale- 4.1 inches.
Ryukin- 6.5 inches.
Vieltail- 4.1 *excluding fins*
Therefore, I can conclude that not only is each breed of Goldfish
different, but also that many people who group fancy Goldfish
into one size class are wrong.
I have made the executive decision to raise one group of the following in the 30 gallon tank, based upon my findings:
Bubble-Eye/Celestial Eye- 3-4
Black Moor- 2
