Ornate pimelodus

Introduction

The Ornate Pimelodus (Pimelodus ornatus), commonly known as the Ornate Pim, is a striking freshwater catfish native to South America. Its distinctive patterns and active nature make it a captivating addition to large home aquariums. While its care requires attention to specific needs, the Ornate Pimelodus rewards dedicated aquarists with its engaging behavior and unique appearance.

Care and Environment

Providing optimal care for the Ornate Pimelodus involves understanding its requirements for tank size, water parameters, diet, and habitat setup.

What is the minimum tank size for an Ornate Pimelodus?

A single Ornate Pimelodus requires a minimum tank size of 540 liters to accommodate its active swimming behavior and potential growth up to 28 cm. For a group, a larger tank is recommended to ensure ample space and reduce territorial disputes.

What are the ideal water parameters for this species?

Maintain water temperatures between 24-27°C, with a pH range of 6.4-7.3, and water hardness between 6-20°dGH. Consistent water quality is crucial, as the Ornate Pimelodus is sensitive to deteriorating conditions.

What type of filtration and lighting does the Ornate Pimelodus require?

A powerful filtration system is essential to handle the high waste output of this species. Moderate lighting is suitable, as the Ornate Pimelodus prefers dimly lit environments with plenty of hiding spots.

What should be included in the tank setup?

Incorporate a fine sandy substrate, driftwood, rock caves, and hardy plants like Anubias or Java fern to mimic its natural habitat. These elements provide necessary hiding places and contribute to the fish's sense of security.

What is the recommended diet for the Ornate Pimelodus?

As an opportunistic feeder, the Ornate Pimelodus thrives on a varied diet of high-quality sinking pellets, flakes, and live or frozen foods such as bloodworms, brine shrimp, and daphnia. Be cautious of overfeeding, as this species is prone to overeating.

Origin and Habitat

The Ornate Pimelodus is widespread throughout northern South America, inhabiting major river systems including the Amazon, Orinoco, and Paraná basins. It favors shallow, flowing waters over sandy or muddy substrates, often found in main river channels, tributaries, and seasonal floodplain lakes. These environments are characterized by soft, slightly acidic water and abundant hiding spots created by submerged driftwood and vegetation.

Temperament and Compatibility

While generally peaceful, the Ornate Pimelodus is a predatory species that may consume smaller tank mates. It is best housed with similarly sized, robust fish such as Silver Dollar Fish, Severum Cichlids, Oscar Fish, and Firemouth Cichlids. Maintaining a small group of Ornate Pimelodus can encourage more active and natural behaviors, as they are naturally shoaling fish.

Is the Ornate Pimelodus aggressive towards other fish?

Although not overtly aggressive, the Ornate Pimelodus may prey on smaller fish that can fit into its mouth. Therefore, selecting appropriate tank mates is essential to prevent predation.

Can the Ornate Pimelodus be kept alone?

While it can survive alone, the Ornate Pimelodus is a shoaling species and exhibits more natural and active behaviors when kept in small groups.

Interesting Facts

The Ornate Pimelodus is known for its striking appearance, featuring three broad, dark bands along its sleek, silver body. It is also capable of producing audible grumbling sounds, especially during feeding or when disturbed. Additionally, this species secretes a toxic mucus, and its pectoral spines can cause painful wounds if handled improperly. Therefore, caution is advised when interacting with this fish.
