Breeding Methods and Key Keeping Techniques for the White Cloud Mountain Minnow
Morphological Characteristics of the White Cloud Mountain Minnow
The White Cloud Mountain minnow, also known as the Baiyun Mountain fish, Tang fish, red-tailed fish, and colorful golden-line fish, belongs to the Cyprinidae family and originates from Guangdong, China.
The White Cloud Mountain minnow was first discovered in the Baiyun Mountain in the northern suburbs of Guangzhou, Guangdong Province, China, hence the name Baiyun Mountain fish.
The White Cloud Mountain minnow is about 3-4 cm long, with a spindle-shaped, slender body that is slightly laterally compressed, a small head, large eyes, and a bluntly rounded snout. The back of the fish is tea-brown with a slight blue tinge, the belly is silvery white, the dorsal fin and caudal fin are bright red, the tips of the pelvic fins are yellow, and the center of the tail is also red. From the tip of the snout backward along the lateral line there is a golden-yellow stripe extending to the end of the caudal peduncle, and in addition there is a golden spot, hence the name golden-line fish.
The White Cloud Mountain minnow has a petite build and brilliant colors, appearing especially beautiful during the juvenile stage, and is known abroad by the laudatory name "rivaling the red neon tetra."
Keeping Requirements for the White Cloud Mountain Minnow
The White Cloud Mountain minnow has a gentle temperament, is omnivorous, and is easy to keep. It is very suitable for beginner keepers. It has no strict requirements for aquarium water; generally slightly acidic or neutral soft water is preferable, with a suitable temperature of 20-25°C, but it can tolerate low temperatures and can survive in water at 5°C.
Although the White Cloud Mountain minnow is omnivorous, it prefers animal-based bait. It is advisable to plant more aquatic plants in the keeping tank and maintain appropriate lighting. The White Cloud Mountain minnow is suitable for mixed keeping with other tropical fish.
Sex Identification and Breeding of the White Cloud Mountain Minnow
Male and female White Cloud Mountain minnows can generally be distinguished by the following characteristics: the male is smaller than the female, but its dorsal fin and anal fin are larger than those of the female, and its body color is also deeper and more brilliant than the female's; the female is plumper than the male, with a swollen belly tinged with white.
A pH of 6.5-7.5, hardness of 6-8, and water temperature of 24°C are suitable; the bottom of the tank should be covered with crushed stone or pebbles, and more aquatic plants such as Myriophyllum and golden-line grass should be planted. The White Cloud Mountain minnow likes to spawn under sunlight, so the breeding tank should be placed where sunlight can reach it.
When breeding, selected pairs of brood fish can be placed in the tank, or group breeding can be used. Each female White Cloud Mountain minnow can lay 150-300 eggs per spawning; after spawning and fertilization, the brood fish must be removed immediately and kept separately to prevent them from swallowing the eggs.
The fertilized eggs hatch into fry after 1-2 days, and after about 3 more days, the fry begin to swim and forage. At first they should be fed with "infusoria water," and it takes about 10 days before they can be fed other small live foods.
