Pink tailed chalceus

Introduction

The Pink tailed chalceus (Chalceus macrolepidotus) is an eye-catching freshwater fish prized by aquarists for its shimmering silver body, striking pinkish-red tail, and active swimming style. Known for their torpedo-shaped bodies and lively presence, Pink tailed chalceus are a favorite for those looking to add movement and color to larger aquariums. While not considered difficult to keep, they do require thoughtful care, particularly regarding tank size and water quality. Their energetic nature and tendency to jump make them a unique but rewarding choice for intermediate hobbyists seeking a dynamic addition to their community tanks.

Care and Environment

Pink tailed chalceus thrive in spacious, well-maintained aquariums that mimic their natural river habitats. The minimum tank volume for a single fish is 200 litres, but a larger aquarium of 400 litres or more is recommended for groups, as these fish are best kept in small shoals. A tight-fitting lid is essential, as Pink tailed chalceus are notorious jumpers and can easily escape if given the chance.

What are the ideal water parameters for Pink tailed chalceus?

They prefer soft to moderately hard freshwater with a temperature range of 23–28°C, a pH between 6.0 and 7.5, and water hardness of 2–15 dGH. Stable water conditions are crucial, as these fish can be sensitive to sudden changes in temperature or chemistry.

How should I set up the tank for Pink tailed chalceus?

Aquarium decor should include open swimming space, as these active fish need room to dart around. Use a sandy or fine gravel substrate, and add driftwood, rocks, and sturdy plants along the edges to provide cover without restricting movement. Strong filtration is recommended to maintain excellent water quality, but avoid excessive current, as Pink tailed chalceus prefer moderate flow. Lighting should be moderate to bright, simulating their natural environment.

What do Pink tailed chalceus eat in captivity?

In the aquarium, they accept a varied diet of high-quality floating pellets, flakes, and live or frozen foods such as bloodworms, brine shrimp, and small insects. Feeding a diverse diet helps maintain their vibrant coloration and overall health.

One challenge with Pink tailed chalceus care is their nervous disposition—they can be skittish and may injure themselves if startled. It’s important to minimize sudden movements around the tank and provide plenty of hiding spots. They rarely show aggression except during feeding or if kept in too small a group, but can be territorial with similar-shaped fish. Regular maintenance and monitoring are key to keeping these fish healthy and stress-free.

Origin and Habitat

Pink tailed chalceus are native to the tropical river systems of northern South America, including the Amazon and Orinoco basins. They are most commonly found in countries like Brazil, Venezuela, Guyana, and Suriname. In the wild, these fish inhabit fast-flowing rivers and streams with clear, oxygen-rich water. Their natural environment features sandy or rocky substrates, submerged driftwood, and overhanging vegetation that provides both shelter and shade.

Do Pink tailed chalceus experience seasonal changes in their habitat?

Yes, their native rivers often experience seasonal flooding, which can affect water depth, flow, and the availability of food sources. This natural variation helps explain their adaptability to a range of water conditions in captivity.

What kind of aquatic plants or decor do they encounter in the wild?

In their natural habitats, Pink tailed chalceus swim among submerged branches, roots, and occasional aquatic plants, which offer protection from predators and strong currents.

Temperament and Compatibility

Pink tailed chalceus are generally peaceful but can be somewhat boisterous, especially when kept in small groups. They are a shoaling species, meaning they feel most secure and display their best colors and behaviors when kept with at least 5 or 6 of their own kind. When kept alone, they may become shy or stressed.

Are Pink tailed chalceus suitable for community tanks?

Yes, they can be kept with other robust, similarly sized fish that share their active temperament. Good tank mates include larger tetras, peaceful cichlids, silver dollars, and catfish. Avoid slow-moving, long-finned, or very small fish, as Pink tailed chalceus may outcompete them for food or mistake them for prey.

Can Pink tailed chalceus be aggressive?

They are not typically aggressive, but minor squabbles can occur within the group, especially if space is limited or during feeding. Providing ample space and keeping them in a proper shoal helps minimize aggression.

To create a harmonious aquarium, ensure all tank mates can tolerate similar water parameters and provide plenty of space and hiding spots to reduce stress and territorial disputes.

Interesting Facts

Pink tailed chalceus have been part of the aquarium trade for decades, admired for their vibrant tails and schooling behavior. In the wild, they are known for their remarkable jumping ability, which helps them escape predators and navigate obstacles. In captivity, this trait means a secure lid is a must!

Do Pink tailed chalceus breed in home aquariums?

Breeding in home aquariums is extremely rare and not well-documented, as they require very specific conditions that are difficult to replicate.

What makes the Pink tailed chalceus unique among freshwater fish?

Their combination of size, speed, and striking coloration sets them apart, making them a centerpiece fish for larger community tanks. Their lively nature and shoaling habits provide endless fascination for aquarists willing to meet their care needs.
