The safest height of goldfish pond

The safest goldfish pond can raise goldfish with a height of more than 30 cm. All kinds of goldfish have different requirements for water level. From an ornamental point of view, goldfish can be divided into two types: overlooking fish and side-looking fish. Generally speaking, 10-25CM fish with lower water level should look down, while fish with higher water level should look from the side.

According to different varieties, 30-80CM water level is needed, such as bronzing 60-80CM water level, Taishi 40-50CM water level, butterfly tail 10-20CM water level and bead 15-20CM water level.

Structural characteristics and functions of goldfish.

Goldfish belongs to the same species as crucian carp in taxonomy. Compared with crucian carp, goldfish has great variation in external morphology, but the whole fish body can be divided into three parts: head, trunk and tail.

The front end of the head is the mouth, and the back is the nose, eyes and gill cover. Some species have sarcoma on the top of the head, some species have villous balls above the nose, some species have prominent eyes, and some species have blisters upward, and some species have gill cover leakage to form gill turnover.

The trunk of goldfish is covered with scales, mainly including normal scales, transparent scales and pearl scales. There is a lateral line on its side, and the scales on the lateral line, the scales under the lateral line and the scales on the lateral line are different in different varieties of goldfish. Typical goldfish have pectoral fins, ventral fins, anal fins, dorsal fins and caudal fins, but some species have no dorsal fins or anal fins. The tail of goldfish consists of a tail handle and a tail fin, and the tail fin has various shapes.
