Five-line loach, also known as STR fish, was discovered by the famous fish scientist Boulenger in 1911. It has five obvious red stripes on its body, hence the name five-line loach. The red stripes on the fish body reflect bright blue or bright green metallic luster depending on the angle of light. In addition, the patterns on the three peculiar fins are also different.
Five-line loach belongs to the heat-resistant variety in the loach family, with a suitable temperature range of 24℃ to 30℃. It has no special requirements for water quality, and a pH value ranging from weak acid to neutral is preferred. However, it is sensitive to drastic changes in water quality.
1. Tail melting disease.
Cause: Deterioration of water quality, growth and reproduction of harmful bacteria, pathogenic bacteria produce powerful protein-decomposing enzymes. The tail is the most fragile tissue of the fish, so it is generally the first to show problems. At this time, it can still be salvaged, but whether it can be saved depends on the situation.
Treatment: Use potassium permanganate or salt diluted with water (usually at a concentration of 0.3-1%), the concentration can be slightly higher. Soak the fish in the solution for about 5 minutes, which is to kill the bacteria. Then put the fish in clean water to rest, and feed it after it recovers its activity. Do not use strong medication, because the fish is already weak in this situation and is likely to die directly if given medication.
Note: The appearance of this phenomenon indicates that the water quality has deteriorated to a certain extent, and water should be changed in time, otherwise it is easy to have a large-scale outbreak.
2. White spot disease:
Also known as ichthyophthyroidism, the characteristics of this disease are rapid transmission, wide prevalence, great harm, and easy treatment. There is no picture of a five-line loach, so I found a picture of a goldfish instead.
Cause: It is caused by external parasites of fish and is a relatively common fish disease. The pathogen of white spot disease is caused by the invasion of the protozoan parasite Ichthyophthirius into the skin or gills of the fish. It generally occurs in spring, autumn, and winter, and this disease may also occur when the water temperature is different during water changes.
Treatment method: This disease spreads quickly, has a wide prevalence, and causes great harm. If it is not discovered in time, it is likely to be wiped out completely. However, if it is discovered in time, it is still easily treatable. The main methods are: raising the water temperature, changing water, and disinfection. Choose one of the three, the same old routines as always.
3. Water mold disease
Characteristics of the disease: Infection of damaged tissues on the body surface, forming a cotton-like covering at the site of injury. The white eggs of the five-line loach are also water mold.
Causes of the disease: This disease is caused by fungi parasitizing the fish's body surface, and it is especially prone to occur when the fish has wounds.
Treatment method: Raise the water temperature to inhibit the growth of fungi, which can effectively treat the disease. Bathing the fish in saltwater or medicated water and then putting it in clean water can also effectively treat the disease. When there is a lot of water mold, the hairy part can be removed. Water mold disease often occurs concurrently with white spot disease.
1. Water Quality: The five-line loach fish is suitable for growth in weakly acidic to neutral water. The pH value of the water should be maintained at 5.5-7 on a daily basis, and the suitable water temperature is 24-30°C. Pay attention to maintaining stable water quality.
2. Feeding: Five-line loach fish prefer to eat animal feed. Worms, bloodworms, and planktonic organisms are good choices. You can also appropriately feed them some plant-based artificial feed to ensure their intake of nutrients is more comprehensive.
3. Environment: Five-line loach fish do not have special requirements for the environment. To provide them with a more beautiful and natural living environment, you can appropriately spread some bottom sand in the fish tank, place some driftwood, or grow some aquatic plants.
