Can Brown Bullhead Catfish and Pungas Catfish Live Together?

Brown Bullhead Catfish is a moderately assertive species (6/10), while Pungas Catfish is generally mild-mannered (3/10). This modest difference means Brown Bullhead Catfish may occasionally assert dominance over Pungas Catfish.

Brown Bullhead Catfish and Pungas Catfish both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Brown Bullhead Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Pungas Catfish is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–20 dGH. Regular testing will ensure conditions stay within this range.

To house Brown Bullhead Catfish and Pungas Catfish together, plan for an aquarium of at least 5000 litres with a minimum length of 450 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Brown Bullhead Catfish and Pungas Catfish need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Feeding time deserves special attention with this pairing. Brown Bullhead Catfish is an aggressive eater that may prevent Pungas Catfish from getting enough food.

Because Brown Bullhead Catfish is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Pungas Catfish receives an adequate share.
