Can your tank handle Peacock Bass Temensis and Rose Danio?

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

Peacock Bass Temensis is a semi-aggressive species (7/10), while Rose Danio is peaceful (1/10). This notable difference means Peacock Bass Temensis may occasionally assert dominance over Rose Danio.

Large aggression gap (6 points) between Peacock Bass Temensis and Rose Danio increases stress risk for the more peaceful fish.

Peacock Bass Temensis and Rose Danio both frequent the Middle (Open Water) and Top (Surface) 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: Peacock Bass Temensis is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 26°C and 26°C. Aim for the midpoint of this range (around 26.0°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 2–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Peacock Bass Temensis and Rose Danio 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), Plants - Densely covered. Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Peacock Bass Temensis and Rose Danio 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 Peacock Bass Temensis and Rose Danio live together?

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

What size tank do Peacock Bass Temensis and Rose Danio need?

A minimum of 3000 litres (tank length at least 300 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 Peacock Bass Temensis and Rose Danio together?

Keep the aquarium between 26°C and 26°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Peacock Bass Temensis or Rose Danio aggressive?

Peacock Bass Temensis is semi-aggressive (7/10) and Rose Danio is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Peacock Bass Temensis and Rose Danio 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.
