Shared Tank Conditions

Mauritius Micro Sword fits inside the water range normally used for Amazon Leaf Fish. The shared window is about 23 to 28 °C, pH 5.5 to 6.8, and 2 to 8 dGH, which gives you enough room to aim for stable middle-ground conditions.

Their flow expectations are close enough to combine: Mauritius Micro Sword prefers moderate flow, while Amazon Leaf Fish prefers gentle, low-flow water.

Both are suited to freshwater, so salinity does not add an extra planning problem.

Fish Pressure and Plant Resilience

Amazon Leaf Fish does not put unusual pressure on this plant compared with harder fish-plant combinations.

Mauritius Micro Sword has high cover density, moderate uproot resistance, and tough / leathery leaves. It can also help with shrimp refuge, fry refuge, grazing surfaces, and spawning sites.

This plant adds the denser cover that Amazon Leaf Fish usually appreciates.

The point to watch is amazon Leaf Fish often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.

Layout Fit

Mauritius Micro Sword is a stolon / runner plant usually used foreground and carpeting.

Amazon Leaf Fish is a fish, so the pairing works best when the planting style supports how that fish uses space and cover.

Mauritius Micro Sword reaches about 10 cm tall by 15 cm wide and is usually rooted in substrate with nutrient-rich substrate preferred. That makes placement and anchoring more important than simply adding a larger bunch of stems or leaves.

In this pairing, the useful plant values are shrimp refuge, fry refuge, grazing surfaces, and spawning sites. Place it where Amazon Leaf Fish can actually use that structure instead of hiding the plant where it cannot do much.

Practical Recommendation

This is a sensible planted-tank choice for Amazon Leaf Fish, especially when you want the plant to do real work as cover, sight-line structure, or habitat detail.

The decision should center on this signal: Amazon Leaf Fish often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.

Best Use Case

Mauritius Micro Sword is a strong choice for Amazon Leaf Fish when you want the plant to do real work in the tank, not just survive in the background. The pairing tends to perform best when the plant's cover, resilience, or placement naturally supports how the fish moves, hides, or claims space.
