Behaviour & Temperament

Common Pleco is a generally mild-mannered species (4/10), while Ghost Shrimp is peaceful (1/10). This modest difference means Common Pleco may occasionally assert dominance over Ghost Shrimp.

Common Pleco and Ghost Shrimp 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.

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

Water Parameters

The safe temperature window for both species falls between 20°C and 28°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 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 5–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Common Pleco and Ghost Shrimp together, plan for an aquarium of at least 600 litres with a minimum length of 150 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Common Pleco is a plant destroyer, which conflicts with Ghost Shrimp's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

What size tank do Common Pleco and Ghost Shrimp need?

A minimum of 600 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 Common Pleco and Ghost Shrimp together?

Keep the aquarium between 20°C and 28°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Common Pleco or Ghost Shrimp aggressive?

Common Pleco is generally mild-mannered (4/10) and Ghost Shrimp is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Common Pleco and Ghost Shrimp need?

Both species overlap in the 6.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Common Pleco's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Common Pleco 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.

Does Common Pleco being nocturnal affect compatibility?

Common Pleco 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 Common Pleco during evening hours.
