Can African Pipefish and Pink Tailed Chalceus Live Together?

African Pipefish is a peaceful species (0/10), while Pink Tailed Chalceus is moderately assertive (6/10). This notable difference means Pink Tailed Chalceus may occasionally assert dominance over African Pipefish.

Large aggression gap (6 points) between African Pipefish and Pink Tailed Chalceus increases stress risk for the more peaceful fish.

In terms of spatial distribution, African Pipefish prefers the Middle (Open Water) and Bottom (Substrate) zones, whereas Pink Tailed Chalceus occupies the Top (Surface) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Pink Tailed Chalceus is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.5. 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.

To house African Pipefish and Pink Tailed Chalceus together, plan for an aquarium of at least 250 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 — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating. Meeting these requirements will help both species thrive.

African Pipefish prefers Low (Still Water) flow while Pink Tailed Chalceus needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
