Can Purple Zebra Shrimp and Silver Flying Fox Live Together?

Purple Zebra Shrimp is a peaceful species (0/10), while Silver Flying Fox is generally mild-mannered (3/10). This modest difference means Silver Flying Fox may occasionally assert dominance over Purple Zebra Shrimp.

Purple Zebra Shrimp and Silver Flying Fox 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Silver Flying Fox 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 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 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 4–15 dGH. Regular testing will ensure conditions stay within this range.

To house Purple Zebra Shrimp and Silver Flying Fox 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.

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

Purple Zebra Shrimp prefers Low (Still Water) flow while Silver Flying Fox needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Purple Zebra Shrimp and Silver Flying Fox need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Feeding time deserves special attention with this pairing. Silver Flying Fox is an aggressive eater that may prevent Purple Zebra Shrimp from getting enough food.

Because Silver Flying Fox is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Purple Zebra Shrimp receives an adequate share.
