Can False Glass Catfish and Neolamprologus Fasciatus Live Together?
False Glass Catfish and Neolamprologus Fasciatus are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle False Glass Catfish and Neolamprologus Fasciatus?
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
False Glass Catfish is a peaceful species (2/10), while Neolamprologus Fasciatus is moderately assertive (6/10). This notable difference means Neolamprologus Fasciatus may occasionally assert dominance over False Glass Catfish.
False Glass Catfish and Neolamprologus Fasciatus 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.
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 False Glass Catfish (5–7) and Neolamprologus Fasciatus (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: False Glass Catfish needs 1–8 dGH while Neolamprologus Fasciatus requires 10–25 dGH.
Tank Setup
To house False Glass Catfish and Neolamprologus Fasciatus together, plan for an aquarium of at least 200 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.
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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Sand (Sifters), Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
Why This Pairing Usually Fails in Practice
False Glass Catfish and Neolamprologus Fasciatus 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.

Frequently Asked Questions
Can False Glass Catfish and Neolamprologus Fasciatus live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do False Glass Catfish and Neolamprologus Fasciatus need?
A minimum of 200 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 False Glass Catfish and Neolamprologus Fasciatus 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 False Glass Catfish or Neolamprologus Fasciatus aggressive?
False Glass Catfish is peaceful (2/10) and Neolamprologus Fasciatus is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do False Glass Catfish and Neolamprologus Fasciatus need?
Their pH requirements do not overlap. False Glass Catfish prefers 5–7, while Neolamprologus Fasciatus needs 7.8–9. This makes them incompatible in the same water chemistry.
How do I manage Neolamprologus Fasciatus's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Neolamprologus Fasciatus 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.
