Can Peacock Bass Temensis and Purple Zebra Shrimp Live Together?

Peacock Bass Temensis is a semi-aggressive species (7/10), while Purple Zebra Shrimp is peaceful (0/10). This notable difference means Peacock Bass Temensis may occasionally assert dominance over Purple Zebra Shrimp.

Large aggression gap (7 points) between Peacock Bass Temensis and Purple Zebra Shrimp increases stress risk for the more peaceful fish.

In terms of spatial distribution, Peacock Bass Temensis prefers the Middle (Open Water) and Top (Surface) zones, whereas Purple Zebra Shrimp occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

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

Worth noting: Peacock Bass Temensis is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°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 Peacock Bass Temensis and Purple Zebra Shrimp together, plan for an aquarium of at least 3000 litres with a minimum length of 300 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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

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

Peacock Bass Temensis and Purple Zebra Shrimp are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
