Can Altolamprologus Compressiceps and Fire Tetra Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 4, 2026
Not Recommended

Altolamprologus Compressiceps and Fire Tetra are not recommended as tank mates due to conflicting pH requirements and piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Altolamprologus Compressiceps and Fire Tetra?

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

Altolamprologus Compressiceps is a moderately assertive species (6/10), while Fire Tetra is peaceful (1/10). This notable difference means Altolamprologus Compressiceps may occasionally assert dominance over Fire Tetra.

Altolamprologus Compressiceps and Fire Tetra both frequent the 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

Water Parameters

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Altolamprologus Compressiceps (7.8–9) and Fire Tetra (5.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Altolamprologus Compressiceps and Fire Tetra together, plan for an aquarium of at least 150 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Shells (Breeding/Hiding), Plants - Densely covered. 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.

Why This Pairing Usually Fails in Practice

Altolamprologus Compressiceps and Fire Tetra are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Diet & Feeding

Feeding time deserves special attention with this pairing. Altolamprologus Compressiceps is a known shrimp eater and may prey on small invertebrates or nano fish like Fire Tetra.

Frequently Asked Questions

Can Altolamprologus Compressiceps and Fire Tetra live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Altolamprologus Compressiceps and Fire Tetra need?

A minimum of 150 litres (tank length at least 90 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 Altolamprologus Compressiceps and Fire Tetra together?

Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.

Are Altolamprologus Compressiceps or Fire Tetra aggressive?

Altolamprologus Compressiceps is moderately assertive (6/10) and Fire Tetra is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Altolamprologus Compressiceps and Fire Tetra need?

Their pH requirements do not overlap. Altolamprologus Compressiceps prefers 7.8–9, while Fire Tetra needs 5.5–7.5. This makes them incompatible in the same water chemistry.

How do I manage Altolamprologus Compressiceps's territorial behaviour?

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