Hard head: hard, dark and opaque (feels like stone). The starting rate is low! It's usually just a small horn shape.

2/

Angle head: translucent appearance, you can clearly see the hard bones inside the forehead. A good variety can have a head shape similar to water head and feel strong muscles! Thick and full.

How to distinguish water head from meat head

(1) shape. location

The water head is large and round, starting from the front end of dorsal fin rising to the upper end of eye and the sunken nose, and rising to the position of fish mouth or even more.

The head of the flesh is small and bulges upward from the depression of the bridge of the nose, but its height will never exceed the height of the dorsal fin, and the forehead bead will never exceed the snout.

2. Touch

Did the water really rise first? It's elastic. The meat head is hard and inelastic.

(3) shoulders

The head and shoulders are wide, while the head and shoulders are narrow and sharp.

(4) Features:

Before the head is organized in the growth stage, it will shrink due to malnutrition, urgency and poor water quality, but it will recover and even continue to grow after stability.

Because it is organized, the meat head is not reduced because of nutrition, urgency and poor water quality, and it belongs to stereotyped forehead beads.
