Can Afra Cichlid and Brown Hoplo Catfish Live Together?

Possible with Caution

Keeping Afra Cichlid and Brown Hoplo Catfish together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 298 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Afra Cichlid and Brown Hoplo 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

Afra Cichlid is a semi-aggressive species (8/10), while Brown Hoplo Catfish is peaceful (2/10). This notable difference means Afra Cichlid may occasionally assert dominance over Brown Hoplo Catfish.

Large aggression gap (6 points) between Afra Cichlid and Brown Hoplo Catfish increases stress risk for the more peaceful fish.

Afra Cichlid and Brown Hoplo Catfish both frequent the Middle (Open Water) and 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.

Worth noting: Brown Hoplo Catfish is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Afra Cichlid and Brown Hoplo Catfish to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. 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 24Β°C and 28Β°C. Aim for the midpoint of this range (around 26.0Β°C) for optimal comfort.

Both fish can tolerate a pH between 7.6 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 10–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Afra Cichlid and Brown Hoplo Catfish together, plan for an aquarium of at least 298 litres with a minimum length of 120 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 β€” caves, driftwood, and dense plant clusters β€” so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). 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 Afra Cichlid and Brown Hoplo Catfish.

Frequently Asked Questions

Can Afra Cichlid and Brown Hoplo Catfish live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 298 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Afra Cichlid and Brown Hoplo Catfish need?

A minimum of 298 litres (tank length at least 120 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 Afra Cichlid and Brown Hoplo Catfish together?

Keep the aquarium between 24Β°C and 28Β°C. A target of around 26.0Β°C sits comfortably within both species' preferred ranges.

Are Afra Cichlid or Brown Hoplo Catfish aggressive?

Afra Cichlid is semi-aggressive (8/10) and Brown Hoplo Catfish is peaceful (2/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Afra Cichlid and Brown Hoplo Catfish need?

Both species overlap in the 7.6–8 pH range. Consistency is key β€” avoid sudden swings, and test regularly to stay within this window.

How do I manage Afra Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Afra Cichlid space to claim a territory without encroaching on the other fish's area. Adding dΓ©cor that divides the tank into distinct zones works especially well.
