Can Saddled Bichir and Tiger Shrimp Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Saddled Bichir and Tiger 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 Saddled Bichir and Tiger 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

Saddled Bichir is a moderately assertive species (6/10), while Tiger Shrimp is peaceful (0/10). This notable difference means Saddled Bichir may occasionally assert dominance over Tiger Shrimp.

Large aggression gap (6 points) between Saddled Bichir and Tiger Shrimp increases stress risk for the more peaceful fish.

Saddled Bichir and Tiger Shrimp 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.

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..

Worth noting: Saddled Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Saddled Bichir is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Saddled Bichir and Tiger Shrimp together, plan for an aquarium of at least 650 litres with a minimum length of 180 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), Plants - Densely covered. Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Usually Fails in Practice

Saddled Bichir and Tiger 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Saddled Bichir and Tiger Shrimp.

Frequently Asked Questions

Can Saddled Bichir and Tiger Shrimp live together?

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

What size tank do Saddled Bichir and Tiger Shrimp need?

A minimum of 650 litres (tank length at least 180 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 Saddled Bichir and Tiger Shrimp together?

Keep the aquarium between 24°C and 25°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.

Are Saddled Bichir or Tiger Shrimp aggressive?

Saddled Bichir is moderately assertive (6/10) and Tiger 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 Saddled Bichir and Tiger Shrimp need?

Both species overlap in the 6–7.4 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Saddled Bichir being nocturnal affect compatibility?

Saddled Bichir is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Saddled Bichir during evening hours.
