Can Amano Shrimp and Black Acara Live Together?

Possible with Caution

Keeping Amano Shrimp and Black Acara together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 115 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Amano Shrimp and Black Acara?

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

Amano Shrimp is a peaceful species (1/10), while Black Acara is moderately assertive (6/10). This notable difference means Black Acara may occasionally assert dominance over Amano Shrimp.

Amano Shrimp and Black Acara 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.

Worth noting: Amano Shrimp is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Amano Shrimp and Black Acara to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

Water Parameters

The safe temperature window for both species falls between 22Β°C and 28Β°C. Aim for the midpoint of this range (around 25.0Β°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 4–14 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Amano Shrimp and Black Acara together, plan for an aquarium of at least 115 litres with a minimum length of 80 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots β€” caves, driftwood, and dense plant clusters β€” so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Established Algae (Otocinclus), Plants - Densely covered, Sand (Sifters), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). 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.

Frequently Asked Questions

Can Amano Shrimp and Black Acara live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 115 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Amano Shrimp and Black Acara need?

A minimum of 115 litres (tank length at least 80 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 Amano Shrimp and Black Acara together?

Keep the aquarium between 22Β°C and 28Β°C. A target of around 25.0Β°C sits comfortably within both species' preferred ranges.

Are Amano Shrimp or Black Acara aggressive?

Amano Shrimp is peaceful (1/10) and Black Acara 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 Amano Shrimp and Black Acara need?

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

How do I manage Black Acara's territorial behaviour?

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