- Ensure there is open swimming space as they are active swimmers.
Substrate:
- A sandy substrate is preferred as it mimics their natural habitat and prevents injury to their delicate barbels.
Disease Prevention:
- Maintain excellent water quality through regular water changes and proper filtration to prevent diseases.
- Quarantine new fish before introducing them to the main tank to prevent the spread of potential diseases.
Filtration:
- Efficient filtration is essential to keep the tank water clean and free from pollutants.
- Consider a combination of mechanical, biological, and chemical filtration for optimal results.
Lighting:
- Redtail Sharks do not have specific lighting requirements but providing a natural day-night cycle with moderate lighting is sufficient.
Water Flow:
- Moderate water flow is ideal to simulate their natural riverine habitat, but avoid strong currents that may stress the fish.
Hardiness:
- Redtail Sharks are relatively hardy fish but can be sensitive to poor water conditions and aggression from tank mates.
Acclimation:
- Proper acclimation is crucial when introducing Redtail Sharks to a new aquarium to minimize stress.
- Float the bag in the tank to equalize temperature before slowly adding tank water to the bag over a period of time.
Expected Lifespan:

- They may form loose groups or shoals but do not require the company of their own species to thrive.
Plant Compatibility:
- Redtail Sharks may uproot or damage delicate plants, especially if they are not provided with enough hiding spots and decor.
- Choose robust plants or provide artificial decor to minimize damage.
Diet and Nutrition
Dry Foods:
- Redtail Sharks readily accept high-quality dry foods such as pellets or flakes formulated for omnivorous fish.
- Look for products specifically designed to meet the nutritional needs of bottom-dwelling species.
Frozen Foods:
- Frozen foods like bloodworms, brine shrimp, and daphnia are excellent options to provide variety and essential nutrients.

Live Foods:
- Redtail Sharks enjoy live foods such as bloodworms, brine shrimp, and blackworms.
- Live foods can be offered as occasional treats to supplement their diet.
Vegetables:
- Redtail Sharks are omnivores and can benefit from blanched vegetables such as zucchini, spinach, and cucumber.
- Ensure vegetables are adequately washed and cut into small, bite-sized pieces before offering them to the fish.
Algae:
- Redtail Sharks may nibble on algae growing in the aquarium, contributing to their dietary variety.
- While they may consume some algae, it should not be their primary source of nutrition.
Feeding Schedule:
- Feed adult Redtail Sharks small amounts of food 2-3 times a day, only offering what they can consume within a few minutes.
- Avoid overfeeding to prevent water quality issues and obesity.
Supplemental Foods:
- In addition to their staple diet, consider offering supplemental foods such as freeze-dried or live foods to provide variety and essential nutrients.
- Rotate through different types of foods to ensure a balanced diet and maintain their health and coloration.
Tank Parameters
Tank Size:
- Redtail Sharks require a tank size of at least 55 gallons (208 liters) to provide ample swimming space and territory.
Tank Length and Measurements:
- A longer tank with dimensions of 48 inches (122 centimeters) or more is preferred to accommodate the Redtail Shark's active swimming behavior.
Water Temperature:
- Maintain water temperature within the range of 72°F to 79°F (22°C to 26°C) for optimal health and activity.
pH (Acidity/Alkalinity):
- Aim for a pH level between 6.5 to 7.5 to replicate their natural freshwater habitat in Southeast Asia.
KH (Carbonate Hardness):
- Carbonate hardness (KH) should be kept stable within the range of 4 to 8 dKH to maintain proper pH levels and buffer against pH fluctuations.
GH (General Hardness):
- General hardness (GH) should be in the range of 5 to 12 dGH to provide essential minerals and support overall fish health.
Hardiness:
- Redtail Sharks are relatively hardy fish but can be sensitive to fluctuations in water parameters, especially pH and temperature.
- Maintaining stable water conditions is crucial for their well-being.
Nitrate (NO3) Levels:
- Keep nitrate levels below 20 ppm (parts per million) through regular water changes and proper filtration to prevent water quality issues and stress on the fish.
History, Popularity, History and Species Variety Details
The History, Popularity, and Natural Habitat:
History: The Redtail Shark, scientifically known as Epalzeorhynchus bicolor, hails from the rivers and streams of Southeast Asia, particularly in Thailand. It was first described by German zoologist Albert Günther in 1868. Initially, the species was not widely known or kept in the aquarium trade. However, as interest in freshwater aquariums grew throughout the 20th century, the Redtail Shark gained popularity among enthusiasts due to its striking appearance and active behavior.
Popularity: The Redtail Shark has become a highly sought-after species in the aquarium hobby due to its captivating coloration and distinct appearance. Its sleek black body contrasted with a vibrant red tail makes it an attractive addition to freshwater tanks. This popularity has led to widespread availability in pet stores and online retailers catering to aquarium enthusiasts. Despite its popularity, it's essential for aquarists to understand and meet the specific care requirements of Redtail Sharks to ensure their health and well-being.
Natural Habitat: In its natural habitat, the Redtail Shark inhabits clear, fast-flowing rivers and streams in Southeast Asia. These freshwater environments are typically characterized by rocky substrates, dense vegetation, and moderate to strong water currents. Redtail Sharks are bottom-dwelling fish, often found among rocks and driftwood where they can seek shelter and establish territories. They are endemic to regions such as the Chao Phraya and Mekong river basins in Thailand.
Similar and Variations of the Species:
- Rainbow Shark (Epalzeorhynchos frenatum): Often confused with the Redtail Shark due to similar body shape and behavior, the Rainbow Shark sports a striking red or orange caudal fin but lacks the distinct black body of the Redtail Shark.
- False Siamese Algae Eater (Epalzeorhynchos kalopterus): This species shares similarities with the Redtail Shark in terms of appearance and behavior but lacks the intense red tail. It has a more subdued coloration and is known for its algae-eating habits.
- Siamese Algae Eater (Crossocheilus oblongus): Although not closely related, the Siamese Algae Eater is often considered a suitable alternative to the Redtail Shark for controlling algae in freshwater aquariums. It has a slender, elongated body and a distinctive black stripe running from its head to tail.
