False blochi catfish
Introduction
The False Blochi Catfish (Corydoras delphax) is a charming and peaceful freshwater fish that has become a favorite among aquarists. Known for its distinctive spotted pattern and active nature, this species adds both visual appeal and dynamic movement to community aquariums. With proper care, the False Blochi Catfish can thrive, making it an excellent choice for both novice and experienced fishkeepers.
Care and Environment
Providing the right environment is crucial for the health and happiness of the False Blochi Catfish. Here's a comprehensive guide to their care:
What is the minimum tank size for a False Blochi Catfish?
A minimum tank size of 100 liters is recommended to accommodate a small group, as these fish are social and prefer to be kept in groups of at least five.
What are the ideal water parameters for this species?
Maintain a temperature between 22°C and 26°C, a pH range of 6.0 to 7.5, and water hardness between 2 to 12 dGH to replicate their natural habitat conditions.
How should the tank be set up to suit the False Blochi Catfish?
Use a soft, sandy substrate to protect their delicate barbels, and include plenty of hiding spots with driftwood, rocks, and dense planting to mimic their natural environment.
Ensure efficient filtration to keep the water clean, as high nitrate levels can lead to barbel erosion. Moderate lighting is sufficient, and regular partial water changes are essential to maintain water quality.
As omnivores, False Blochi Catfish thrive on a varied diet. Provide high-quality sinking pellets or granules, supplemented with live or frozen foods like bloodworms, brine shrimp, and daphnia. Occasional vegetable matter, such as spirulina wafers, can also be beneficial.
Origin and Habitat
The False Blochi Catfish is native to South America, specifically the Inírida River and upper Orinoco River basin in Colombia. In the wild, they inhabit shallow, slow-flowing waters with sandy or silty bottoms, often covered with leaf litter and submerged wood. These environments are typically rich in vegetation, providing ample hiding spots and foraging opportunities.
Temperament and Compatibility
False Blochi Catfish are peaceful and sociable, making them excellent additions to community aquariums. They are shoaling fish and should be kept in groups of at least five to promote natural behaviors and reduce stress.
Are False Blochi Catfish compatible with other fish species?
Yes, they coexist well with other peaceful species that share similar water parameter requirements, such as small tetras, rasboras, and other non-aggressive fish.
Do they exhibit any aggressive behaviors?
No, they are known for their docile nature and do not display aggression towards tank mates.
How can I create a harmonious tank environment for them?
Ensure the tank is spacious enough to accommodate all inhabitants comfortably, provide plenty of hiding spots, and maintain stable water conditions to keep all fish stress-free.
Interesting Facts
False Blochi Catfish possess a unique ability to breathe atmospheric air by gulping it at the water's surface, allowing them to survive in low-oxygen environments. This behavior is common among Corydoras species and is fascinating to observe in the aquarium setting.
During breeding, they exhibit the characteristic "T-position," where the male fertilizes the eggs held between the female's pelvic fins before she attaches them to surfaces like plant leaves or tank glass.
The species name "delphax" translates to "young pig" or "piglet," a nod to their enthusiastic foraging behavior, as they are often seen rooting through the substrate in search of food.
