Tocantinsia Piresi Catfish

The Tocantinsia piresi is a really unique South American catfish known for its dark body covered in bright cream or gold spots and long flowing fins. It has a very “wild” look to it and becomes a real centerpiece fish once it gets some size. Even though it looks aggressive, it’s actually a pretty calm species when kept with the right tank mates. This fish does best in larger aquariums with driftwood, strong filtration, and good water movement. They spend a lot of time resting on wood or cruising around the bottom of the tank. Max Size Usually around 12–16 inches in captivity, sometimes larger in big systems. Tank Size Minimum: 125 gallons Recommended: 180+ gallons for adults A larger footprint is important since they get pretty bulky and active. Tank Mates Peaceful for their size and usually do well with other larger community fish. Good tank mates include: Silver Dollars Severums Geophagus Larger tetras Other peaceful catfish or plecos Avoid: Very aggressive fish Small fish that may get stressed around them Overcrowded bottom dwellers Diet Mostly omnivorous with a strong preference for plant-based foods and natural grazing. Good foods include: Algae wafers Quality sinking pellets Zucchini or cucumber Spinach Cut shrimp occasionally Occasional protein foods in moderation Driftwood is also important since they naturally graze on surfaces throughout the day. 👉 A varied diet helps keep them healthy and brings out their patterning. Care & Behavior These catfish are hardy once established, but they need clean, well-oxygenated water. They usually become more outgoing over time and can even recognize feeding routines. They enjoy: Driftwood Moderate to strong flow Dimmer lighting Open bottom space Because of their size, they produce a decent amount of waste, so strong filtration and regular maintenance are important.
