Red Tail Shark Basic Care
Habitat Requirements
Red Tail Sharks are native to the rivers and streams of Thailand, where they swim in strong currents with ample hiding places. In captivity, they require at least a 30-gallon tank with plenty of hiding spots like caves, rocks, and plants.
Tank Setup
A planted tank with ample swimming space and hiding spots is ideal for Red Tail Sharks. Make sure there’s enough space for them to swim without overcrowding the tank.
Water Conditions
Maintaining the right water conditions is crucial for the health of your Red Tail Shark. They require water with a pH of between 6.5 and 7.5 and a temperature between 72°F and 82°F. Additionally, a good filtration system is essential to keep the water clean.
Feeding
Red Tail Sharks are omnivorous and will eat anything from flakes to live worms, shrimp, and small fish. Feed them twice a day with high-quality flakes or pellets and supplement their diet with live or frozen foods.
Health and Diseases
Red Tail Sharks are generally healthy fish, but they can be prone to common fish diseases if their water conditions aren’t right or their diet isn’t adequate. Keep an eye out for common issues like ich, fin rot, and swim bladder disease. Consult a vet or professional immediately if you suspect your fish is ill.
Red Tail Shark Behavior and Temperament
Are Red Tail Sharks Aggressive?

Red Tail Sharks and Other Fish
Red Tail Sharks can coexist peacefully with other species as long as there’s enough space and hiding spots in the tank. They tend to get along with larger, peaceful fish like Plecos, Cichlids, and Rainbowfish.
Keeping Multiple Red Tail Sharks
Red Tail Sharks should be kept singly or in groups of at least three in a larger tank with ample space. A smaller tank will lead to territorial behavior and aggression.
