If your ranchu tio stunned, then also won't grow anymore. The symptom will be the eye pupil grow until big big but the body stops at the size it was stunned.

The tails and fins will usually be larger than normal too.

I think that 8-10 cm is very small for a Ranchu. A Tosai should be at least 8-10 cm. There are Nisai of 18 cm and more.
All Ranchu can become big as long as they are well taken care of. Size does of course depend on the bloodline. Some bloodlines become 25 cm and more. Mr. Tashiro Ranchu have the reputation to become very big. The All Japan East Ozeki 2003 was around 30 cm !

Excellent answer. Allow me to add a little. The bigger the pond, the bigger your fish. I have a Nisai that's 20 cms right now and she will grow more from the looks of things. In my ponds there are quite a few fish from all the major Japanese farms but I am able to raise them to all grow over 18 cms. There are many ranchu that will remain dwarf. A lot of the fish that I have bought from Japan, are sometime dwarf. (Be careful with small fish that has really small scales and great color and head growth, but really large eyes in comparision with the size of the fish. That's one sure way of finding out dwarf fish. However, this is not full proof.
Cheers.

Pat,
you mentioned the bigger the pond, the bigger the fish. could you give us some rough ratio, how many gallons of water are needed for 1 fish to reach its fullest potential?

Like my pond it's 3 tons of water. The system is similar to koi pond but I do not use the vortex system. The pond is very big but the whole pond is no deper than 45 cms. I keep no more than 30 fish in the pond.

I also used to keep fish in fiberglass pond, as well. In a pond that's 1.5m x 1.2m x 35 cms, I keep no more than 3 adult size fish, and no more than 12 small fish in there. In a smaller fiberglass pond 1.1m x .9m x 35 cms. I keep no more than 2 adult size fish and no more than 10 smaller fish.

As it was pointed out earlier, all of the elements will aid in promoting the right growth pattern. That's what make the fish grow really big. If the fish is healthy and you are taking good care of of the fish, the fish will grow to the biggest possible size for your pond size. (It is not easy to grow fish bigger than 20 cms.)
