Behaviour & Temperament

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while American Grass Shrimp is peaceful (1/10). This notable difference means Agassiz's Dwarf Cichlid may occasionally assert dominance over American Grass Shrimp.

Agassiz's Dwarf Cichlid and American Grass 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

Worth noting: American Grass 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 Agassiz's Dwarf Cichlid and American Grass Shrimp 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 24Β°C and 28Β°C. Aim for the midpoint of this range (around 26.0Β°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Agassiz's Dwarf Cichlid and American Grass Shrimp together, plan for an aquarium of at least 60 litres with a minimum length of 60 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: Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.

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

What water temperature is best for Agassiz's Dwarf Cichlid and American Grass Shrimp together?

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

Are Agassiz's Dwarf Cichlid or American Grass Shrimp aggressive?

Agassiz's Dwarf Cichlid is moderately assertive (5/10) and American Grass Shrimp is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Agassiz's Dwarf Cichlid and American Grass Shrimp need?

Both species overlap in the 6.5–7 pH range. Consistency is key β€” avoid sudden swings, and test regularly to stay within this window.

How do I manage Agassiz's Dwarf Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Agassiz's Dwarf Cichlid 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.
