Reviewed by Guidarium Editorial DeskUpdated May 7, 2026
Not Recommended

Ninja Shrimp and Sulphur Crest Lithobates are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Ninja Shrimp and Sulphur Crest Lithobates?

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

Ninja Shrimp is a peaceful species (0/10), while Sulphur Crest Lithobates is moderately assertive (6/10). This notable difference means Sulphur Crest Lithobates may occasionally assert dominance over Ninja Shrimp.

Large aggression gap (6 points) between Ninja Shrimp and Sulphur Crest Lithobates increases stress risk for the more peaceful fish.

Ninja Shrimp and Sulphur Crest Lithobates 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.

Water Parameters

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Ninja Shrimp (6.5–7.5) and Sulphur Crest Lithobates (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Ninja Shrimp and Sulphur Crest Lithobates 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: Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Sand (Sifters). 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

Ninja Shrimp and Sulphur Crest Lithobates 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.

Frequently Asked Questions

Can Ninja Shrimp and Sulphur Crest Lithobates live together?

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

What size tank do Ninja Shrimp and Sulphur Crest Lithobates 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 Ninja Shrimp and Sulphur Crest Lithobates together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Ninja Shrimp or Sulphur Crest Lithobates aggressive?

Ninja Shrimp is peaceful (0/10) and Sulphur Crest Lithobates is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Ninja Shrimp and Sulphur Crest Lithobates need?

Their pH requirements do not overlap. Ninja Shrimp prefers 6.5–7.5, while Sulphur Crest Lithobates needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage Sulphur Crest Lithobates's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Sulphur Crest Lithobates space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
