  • They have a compact, slightly flattened body with an elongated snout and small barbels.
  • Aspidoras rochai is relatively small, growing to about 1.5 to 2 inches in length when mature.

Species Overview

The Aspidoras rochai, a member of the Corydoradinae sub family of catfish, belongs to the Callichthyidae family. These fish originates from the rivers of Brazil in South America.

These fish have a compact and slightly flattened body shape with an elongated snout and small barbels. Their dorsal fin, located on the top of their bodies, may display dark markings, while the other fins are generally transparent.

Physical Characteristics

One notable characteristic of Aspidoras rochai is the presence of horizontal bands that span across their bodies. These bands create an eye-catching pattern against their pale background coloration, enhancing their overall aesthetic appeal.

Aspidoras rochai possess a compact body shape, which allows them to maneuver easily through dense vegetation in their aquatic environment. This streamlined physique enables them to navigate between rocks and dense vegetation in search of food and shelter.

With an elongated snout and small barbels, Aspidoras rochai use their sensory organs to detect prey and navigate their surroundings. The elongated snout aids in digging through substrates in search of food particles, while the small barbels help them sense changes in water conditions.

Size, Growth Rate, and Lifespan

These small fish typically grow to a length of about 1.5 to 2 inches (3.8 to 5 centimeters) when fully mature. They boast a pale or light-colored body adorned with distinctive dark markings or bands that run horizontally across their bodies.

Rocha’s Catfish is a relatively slow-growing species. In optimal conditions, you can expect them to reach their adult size of about 1.5 to 2 inches (3.8 to 5 centimeters) within approximately 1 to 1.5 years.

They can live for up to 5 to 8 years or even longer in some cases. Factors such as water quality, temperature, and the fish’ diet can influence their growth rate.

Habitat and Tank Conditions

Aspidoras rochai is a species native to inland waters, the slow-moving coastal rivers, and streams of Brazil’s Amazon basin in South America. These fish are found in both inland waters and coastal rivers.

Remember that each fish has its own preferences and requirements. Observing their behavior closely will help you make adjustments if needed.

By recreating their natural habitat and providing optimal tank conditions, you’ll create a comfortable environment where your Aspidoras rochai can thrive.

Water Parameters

Rocha’s Corydoras prefer soft, acidic water conditions with temperatures ranging from 72°F to 79°F (22°C to 26°C). Maintaining a pH level around 6.0 to 7.0 is ideal for their health and well-being.

Like many other catfish species, these fish are generally adaptable to a range of water hardness levels. Ideally, keep the GH in the range of 2 to 15 dGH (degrees of general hardness) and maintain the KH in the range of 2 to 12 dKH (degrees of carbonate hardness).

Substrate and Decor

To mimic their natural habitat, it is recommended to provide a sandy or fine-gravel substrate in the tank. This type of substrate is gentler on their sensitive barbels and allows them to exhibit natural behavior such as sifting through the sand for food. A depth of at least two inches of substrate is recommended.

Creating hiding places within the tank is important for Aspidoras rochai’s sense of security. Adding caves or driftwood provides them with shelter where they can retreat when feeling stressed or threatened. It also gives them opportunities for exploration and play.

Tank Maintenance

In addition to these considerations, it’s essential to maintain good water quality by regularly testing ammonia, nitrate, nitrite levels, and performing regular water changes. Providing a balanced diet that includes high-quality sinking pellets or frozen foods will ensure their nutritional needs are met.

Tankmates and Temperament

Aspidoras rochai, also known as the Rocha’s Corydoras, are peaceful little fish that make great additions to community tanks. These bottom-dwelling fish spend most of their time foraging for food on the substrate, making them a fascinating species to observe.

Behavior

Aspidoras rochai thrive in social settings and should be kept in groups of at least six individuals. This allows them to engage in natural behaviors and promotes a sense of security within the group. The presence of other Aspidoras rochai will encourage exploration and activity levels.

Rocha’s Catfish have a peaceful temperament and prefer calm environments. It’s essential to avoid keeping them with larger, aggressive species that may harm or intimidate them. Aggressive tankmates can cause stress and even physical damage to these delicate fish.

Compatible Companions

These bottom-dwelling catfish are generally peaceful and can coexist with a variety of other fish species. Choose tankmates that occupy different areas of the water column. This helps minimize competition for resources such as food and territory.

Here are some examples of suitable tankmates for the Aspidoras rochai:

Corydoras species: Aspidoras rochai are part of the Corydoradinae sub family, so they can be housed with the family of other Corydoras catfish species. Some popular choices include Corydoras paleatus (Peppered Cory), Corydoras sterbai (Sterba’s Cory), and Corydoras julii (Julii Cory).

Tetras: Many tetra species make great tankmates for Aspidoras rochai. Some compatible options include Neon Tetras, Black Neon Tetras, Ember Tetras, and Glowlight Tetras. These small, schooling fish add color and activity to the tank.

Rasboras: Peaceful rasboras species like Harlequin Rasboras and Chili Rasboras can coexist with Aspidoras rochai. These fish are also schooling species, so it’s recommended to keep them in groups of at least six for their well-being.

Dwarf Gouramis: These small, labyrinth fish can be a great addition to a tank with Aspidoras rochai. The peaceful nature of Dwarf Gouramis makes them compatible tankmates, and their vibrant colors add visual interest to the aquarium.

Kuhli Loaches: These quirky, eel-like fish are bottom-dwellers like the Aspidoras rochai. They are peaceful and enjoy similar tank conditions, making them suitable companions. Kuhli Loaches are nocturnal, so they can provide some activity during the night.
