During the ranchu's early development, active feeding with a variety of foods is essential. Among the many, two foods are of most importance: fresh or frozen bloodworms and green algae. That is what directly effects the overall head growth, including funtan. While frozen bloodworms are readily available at the pet stores, green algae needs to be "cultivated" on the tank's walls and floor. Sufficient light and fish waste will do the trick. Soon enough, every surface in the tank will start getting covered with one of the best food supplements for ranchu - an assortment of algae.

But the job of "building" impressive head growth doesn't end after the ranchu pass through their BBR stage. As I have mentioned in my earlier posts, the head growth continues to develop throughout the ranchu life and can get rather big. It is necessary to foresee what the baby ranchu will look like when they are older by evaluating their head growth and feeding it bloodworms accordingly. For some, the head growth development needs to be slowed down and for some accelerated, by changing the feeding pattern.

Below is an example of one of my female ranchu with lack of proper head growth at three months. Despite her smaller and narrower head shape it was still possible to increase the head growth quite considerably by eleven months. Feeding her bloodworms and high protein pellets did the job. More work is needed. I hope by the oya age she will have a nice and balanced head.

In the case of my eleven months old ranchu male below,  I might not want to stimulate his head growth from now on, as I would rather see it develop slower and not become unbalanced with his body in his oya age. We will see what happens in a year, but for now that is what I am hoping for.
