Can Bullseye Catfish and Pictus Catfish Live Together?

Possible with Caution

Keeping Bullseye Catfish and Pictus Catfish together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 450 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Bullseye Catfish and Pictus Catfish?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Bullseye Catfish is a moderately assertive species (6/10), while Pictus Catfish is generally mild-mannered (4/10). This modest difference means Bullseye Catfish may occasionally assert dominance over Pictus Catfish.

Bullseye Catfish and Pictus Catfish both frequent the Bottom (Substrate) and Middle (Open Water) 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Bullseye Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

Water Parameters

The safe temperature window for both species falls between 23°C and 26°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bullseye Catfish and Pictus Catfish together, plan for an aquarium of at least 450 litres with a minimum length of 150 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: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Floating, Sand (Sifters). 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Bullseye Catfish and Pictus Catfish.

Frequently Asked Questions

Can Bullseye Catfish and Pictus Catfish live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 450 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Bullseye Catfish and Pictus Catfish need?

A minimum of 450 litres (tank length at least 150 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Bullseye Catfish and Pictus Catfish together?

Keep the aquarium between 23°C and 26°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.

Are Bullseye Catfish or Pictus Catfish aggressive?

Bullseye Catfish is moderately assertive (6/10) and Pictus Catfish is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Bullseye Catfish and Pictus Catfish need?

Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Bullseye Catfish being nocturnal affect compatibility?

Bullseye Catfish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Bullseye Catfish during evening hours.
