Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Pink Tailed Chalceus and Red Tupfel Shrimp are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Pink Tailed Chalceus and Red Tupfel Shrimp?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

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

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

In terms of spatial distribution, Pink Tailed Chalceus prefers the Top (Surface) zone, whereas Red Tupfel Shrimp occupies the Bottom (Substrate) and Middle (Open Water) zones. 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: Shrimp eaters may also prey on very small nano fish.

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

Water Parameters

The safe temperature window for both species falls between 23°C and 25°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 5–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Pink Tailed Chalceus and Red Tupfel Shrimp 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.

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), Plants - Floating, Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Pink Tailed Chalceus and Red Tupfel 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.

Diet & Feeding

Feeding time deserves special attention with this pairing. Pink Tailed Chalceus is a known shrimp eater and may prey on small invertebrates or nano fish like Red Tupfel Shrimp.

Frequently Asked Questions

Can Pink Tailed Chalceus and Red Tupfel Shrimp live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Pink Tailed Chalceus and Red Tupfel Shrimp need?

A minimum of 250 litres (tank length at least 120 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 Pink Tailed Chalceus and Red Tupfel Shrimp together?

Keep the aquarium between 23°C and 25°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Pink Tailed Chalceus or Red Tupfel Shrimp aggressive?

Pink Tailed Chalceus is moderately assertive (6/10) and Red Tupfel Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Pink Tailed Chalceus and Red Tupfel Shrimp need?

Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
