Striped Woodcat (Trachelyopterichtys taeniatus)

Trachelyopterichthys taeniatus – Striped Woodcat

The Striped Woodcat is a sleek, nocturnal South American catfish prized for its elongated body and elegant horizontal striping. Native to slow-moving tributaries and flooded forests, this species spends much of the day tucked under driftwood or in shaded areas, becoming more active at dusk.

Unlike many larger predatory catfish, the Striped Woodcat remains manageable in size and can work well in peaceful to semi-aggressive community aquariums when given proper space. Its subtle patterning and whiskered face give it a classic “Amazon river” look, making it an excellent addition to natural or blackwater-style setups.

Calm but opportunistic, this species thrives in well-maintained aquariums with stable water conditions and plenty of cover.

Tank Mates

Striped Woodcats are peaceful but will eat very small fish.

Good tank mates:

• Medium-sized tetras

• Peaceful cichlids

• Silver dollars

• Larger rasboras

• Other peaceful catfish

Avoid:

• Very small fish (may be eaten)

• Aggressive cichlids

• Fin-nipping species

• Overly territorial bottom dwellers

Best paired with fish too large to fit in their mouth but calm enough not to harass them.

Feeding

Omnivorous leaning carnivorous.

• Sinking carnivore pellets

• Frozen foods (bloodworms, brine shrimp, chopped shrimp)

• Occasional live foods

• Some vegetable-based foods accepted

Feed in the evening for best response, as they are most active after lights out.
