Is Micro Sword a Good Plant for Red Eye Tetra?

Micro Sword fits inside the water range normally used for Red Eye Tetra. The shared window is about 22 to 28 °C, pH 6 to 7.5, and 3 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.

Both do best with moderate flow, so circulation does not need to be split into competing zones.

Water type can work if the tank stays in the shared part of freshwater to lightly brackish water and freshwater conditions.

Red Eye Tetra can still be rough on plants, but this pairing becomes more realistic when the plant is anchored well and used as part of a larger layout.

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

Micro Sword is less tempting than softer, more palatable plants for known nibblers.

The point to watch is red Eye Tetra may still investigate the plant, but the tougher foliage gives it a better chance.

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

Red Eye Tetra is a characin, so the pairing works best when the planting style supports how that fish uses space and cover.

Micro Sword reaches about 7 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 Red Eye Tetra can actually use that structure instead of hiding the plant where it cannot do much.

This is a sensible planted-tank choice for Red Eye Tetra, 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: Red Eye Tetra may still investigate the plant, but the tougher foliage gives it a better chance.

Micro Sword is a strong choice for Red Eye Tetra 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.
