Currently, this male Oya ranchu is close to 6 in (15 cm) long. As you can see, nothing much changed in his body and tail shape, other than him getting bigger. The head has formed into Shishigashira type, which is somewhat vintage for a modern ranchu. His tail, however, ended up with more red markings.
As NISAI fish transitions to OYA, it is harder and harder to keep them in shape. While the tail may not have any dramatic changes with age, the body and head do. My goal is to raise "lean" TVR. I prefer the body outline, as viewed from above, to be more elongated, with no protruding belly, so that the sides from head to beginning of O-Tsutsu (tail peduncle) are somewhat parallel. I also like it if the head width stays not much wider than the width of the back, a cigar shape.
From the side, I like Se-Koshi (back curvature) to be as flat as possible up to the start of O-Tsutsu (tail peduncle). Reminiscent of a long Japanese boxwood comb. For body parts terminology please click here.
Quality of food and its portioning, along with exercise, is crucial to keeping ranchu in good shape. I will write about this subject in a separate article, reflecting on my experience.
