Ryukin goldfishs hump, how long till it is prominent?


Question
Can you tell me or refer to someone who would know how long it will take for
my ryukin's hump to develop, he is a little over one inch long now and i was
just wondering how long it may take? thanks

Answer
It will become more prevalent as the goldfish grows older.  A one inch goldfish is still pretty tiny.  I would say that by four inches, the fish should have a pretty obvious hump behind the head (up to the back).  A ryunkin may take 2 to 5 years to grow to 4 inches depending on temperature, water quality, food, and more.

Good luck!
