Can Brevis Shelldweller and Neon Blue Cichlid Live Together?
Keeping Brevis Shelldweller and Neon Blue Cichlid together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 150 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Can your tank handle Brevis Shelldweller and Neon Blue Cichlid?
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
Brevis Shelldweller is a moderately assertive species (5/10), while Neon Blue Cichlid is generally mild-mannered (3/10). This modest difference means Brevis Shelldweller may occasionally assert dominance over Neon Blue Cichlid.
Brevis Shelldweller and Neon Blue Cichlid 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.
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 Brevis Shelldweller and Neon Blue Cichlid to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.
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.
Both fish can tolerate a pH between 8 and 9. 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 Brevis Shelldweller and Neon Blue Cichlid 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.
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), Shells (Breeding/Hiding), 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.

What water temperature is best for Brevis Shelldweller and Neon Blue Cichlid 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 Brevis Shelldweller or Neon Blue Cichlid aggressive?
Brevis Shelldweller is moderately assertive (5/10) and Neon Blue Cichlid is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Brevis Shelldweller and Neon Blue Cichlid need?
Both species overlap in the 8–9 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Brevis Shelldweller's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Brevis Shelldweller 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.
