Catfish – Common Bristlenose Catfish 4-5cm

Bristlenose Catfish (Ancistrus sp.)

The Bristlenose Catfish is a hardy freshwater species celebrated for its algae-eating abilities and unique appearance. Ideal for beginner and experienced aquarists, this peaceful fish helps maintain tank cleanliness while adding a distinctive touch.

Appearance

These catfish are known for their flattened bodies and prominent bristles, most pronounced in males. Their coloration ranges from brown to black, often with lighter spots. Females typically have fewer or no bristles, making it easy to differentiate sexes. Growing up to 10–15 cm, they are manageable in most aquariums.

Care Requirements for the Bristlenose Catfish

To ensure these catfish thrive, provide a tank of at least 100 liters with caves, driftwood, and hiding spots. Driftwood is essential as it aids digestion and provides surfaces for grazing. Maintain water conditions with a pH of 6.5 to 7.5 and temperatures between 22°C and 27°C. Strong filtration and moderate lighting are key to keeping them healthy.

Tank Mates

The peaceful nature of this species makes it compatible with a variety of tank mates, including tetras, rasboras, guppies, and Corydoras catfish. Avoid pairing them with aggressive or predatory species to prevent stress or harm.

Feeding and Nutrition

These catfish primarily feed on algae and plant matter. Sinking algae wafers, fresh vegetables like zucchini or spinach, and occasional pellets provide a balanced diet. Remove any uneaten food to maintain water quality.

Breeding Tips

Breeding Bristlenose Catfish is relatively easy. Males guard the eggs, which are typically laid in caves. Eggs hatch within 4–10 days, and the fry feed on powdered algae or baby brine shrimp. Providing ample hiding spaces encourages successful breeding.
