The greatest fun of raising Arowanas is the interaction with each other and the change of body shape at each stage of growth.Among them, the beauty of the scales occupies a huge factor, which can be roughly divided into color and integrity.The color part has the opportunity to discuss with you in the future, and the complete part is the content to be discussed in this post.In terms of arowana species, the probability of erosion scales (incomplete scales) of golden arowanas is greater than that of red arowanas (this is related to the degree of water quality requirements).We have summarized the following conditions: 1. Semi-moon-shaped defects The cause of this symptom is bacterial infection. The most obvious feature is that the scales show large-scale semi-moon-shaped defects and most of them are concentrated in rows 3 to 6 (from bottom to top)(Calculation), sometimes it may be accompanied by scalp corrosion and whitening, the condition is similar to skin disease, you need to be extra careful.2. Sawtooth defect The cause of this symptom is poor water quality or bacterial infection or vitamin deficiency. The most obvious feature is the sawtooth corrosion on the edge of the scales. If the condition is serious, it may dissolve the scale frame completely. Do not take it lightly.3. Thinning of scales The cause of this symptom is bacterial infection. The most obvious feature is the spread from the inner edge of the scales to the surroundings. The color of the outer surface of the affected area disappears and thins, and the white scale matrix can be directly observed.4. Corrosion of the scale surface This symptom is caused by bacterial infection. The most obvious feature is the appearance of pits of different sizes on the outer surface of the scale.5. The scales are black. The cause of this symptom is PH oscillation or KH oscillation. The most obvious feature is the irregular black stripes on the outer surface of the scales, which are mostly concentrated under the back and dorsal fin. If not treated as soon as possible, it may cause bacterial infections.This in turn causes scale corrosion.6. Scaled edge corroded hematoma The cause of this symptom is bacterial infection. The most obvious feature is the severe corrosion of the scale edge, and the surface is covered with mucus. Treatment: If the above arowana scales appear, you need to change the water as soon as possible with a small number of water changes as soon as possible, then add yellow powder for anti-inflammatory and sterilization treatment.Arowana vitality, promote appetite!
