Introduction
Pictus Catfish are fast, energetic, and fascinating bottom-dwellers with long barbels and a sleek, silver body speckled with black spots. Native to South America, they bring movement and character to mid- to large-sized aquariums. However, choosing the right tank mates is key—Pictus are semi-aggressive and may eat smaller fish if given the chance.
This guide covers the best tank mates for Pictus Catfish, species to avoid, and tips on building a peaceful, well-balanced community tank.

Best Tank Mates for Pictus Catfish

Top Compatible Tank Mates:
- Silver Dollar Fish: Peaceful, schooling, and too large to be eaten
- Rainbowfish: Fast, colorful, and surface dwellers
- Gouramis (Larger Species): Like Pearl and Blue Gouramis – calm and mid-level swimmers
- Large Tetras: Buenos Aires or Congo Tetras – active and resilient
- Angelfish: As long as they’re not too small (avoid young or nano-size angels)
- Firemouth Cichlids: Mildly territorial but can co-exist with Pictus in larger tanks
- Bristlenose Plecos: Peaceful bottom-dwellers that mind their own business
- Rope Fish: Unique tankmate, similar activity level, and generally peaceful
Tank Mates to Avoid
Some fish just won’t work with a Pictus Catfish. Whether due to size, aggression, or water parameter mismatches, avoid the following:
Species to Avoid:
- Small Tetras (Neons, Ember): Easily mistaken for food
- Shrimp and Snails: Will be eaten or harassed
- Betta Fish: Too slow and prone to fin damage
- Oscars or Green Terrors: Overly aggressive and territorial
- Discus: Too delicate for the fast-paced nature of Pictus
Tank Setup Tips for Compatibility
1. Tank Size and Space
- Minimum of 55 gallons for 1–2 Pictus, 75+ gallons for a group
- Long tanks are better than tall ones—more swimming room
2. Provide Hiding Spots
- Use driftwood, caves, and PVC tubes for daytime hiding
- Add plants along the sides to create natural barriers
3. Water Parameters
| Parameter | Ideal Range |
|---|---|
| Temperature | 74–80°F (23–27°C) |
| pH | 6.5–7.5 |
| Ammonia/Nitrite | 0 ppm |
| Nitrate | < 30 ppm |
4. Feed Generously and Fairly
- Pictus Catfish are carnivores—use sinking pellets, frozen bloodworms, and brine shrimp
- Feed tank mates floating or mid-level food to avoid competition
Mid-Article Tip: Want a Self-Cleaning Community Tank?
Instead of relying on filters alone, try balancing your tank with live plants that clean the water for you. Aquaponics 4 You shows you how to set up a naturally filtered aquarium where plants use fish waste as fertilizer—creating a stable, low-maintenance ecosystem your Pictus Catfish will thrive in.
Can Pictus Catfish Live Alone?
Technically yes, but they prefer groups. Pictus Catfish are social by nature. Keeping at least 3 together helps reduce stress, encourages natural behavior, and keeps them active. However, more fish means more space is required.
Can You Keep Pictus Catfish with Cichlids?
You can—but only with the right species. Stay away from overly aggressive cichlids like Oscars or African varieties. Stick to less territorial options like Firemouths, Keyholes, or Severums in a large enough tank with lots of cover.
Signs of Tank Mate Incompatibility
- Fin nipping or chasing
- Pictus hiding all the time (may be bullied)
- Missing small fish (likely eaten at night)
- Sudden aggression during feeding
If you notice these signs, it may be time to rehome or rearrange your tank setup.
Conclusion: Build a Balanced Tank That Works
Pictus Catfish are bold, fast, and always on the move—but with the right tank mates, they make amazing community fish. Choose companions that are too big to eat, peaceful enough to avoid fights, and fast enough to compete for food. Always provide space and hiding spots, and you’ll enjoy a beautiful, energetic tank with minimal drama.
