Can Cherry Shrimp and Peacock Gudgeon Live Together?
Keeping Cherry Shrimp and Peacock Gudgeon together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 48 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Cherry Shrimp is a peaceful species (0/10), while Peacock Gudgeon is peaceful (2/10). This modest difference means Peacock Gudgeon may occasionally assert dominance over Cherry Shrimp.
Cherry Shrimp and Peacock Gudgeon both frequent the Bottom (Substrate) and 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.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
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.
Water Parameters
The safe temperature window for both species falls between 22°C and 26°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 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 6–10 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Cherry Shrimp and Peacock Gudgeon together, plan for an aquarium of at least 48 litres with a minimum length of 45 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). 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.
