Is Anubias Barteri a Good Plant for Swordtail?

Anubias Barteri fits inside the water range normally used for Swordtail. The shared window is about 21 to 28 °C, pH 7 to 8, and 12 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 and freshwater to lightly brackish water conditions.

Swordtail does not put unusual pressure on this plant compared with harder fish-plant combinations.

Anubias Barteri has moderate cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines, spawning sites, grazing surfaces, and shrimp refuge.

This plant adds the denser cover that Swordtail usually appreciates.

There is no special plant-pressure warning here, so solid anchoring and stable husbandry matter more than unusual protection.

Anubias Barteri is a rhizome / epiphyte plant usually used midground, background, and attached to hardscape.

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

Anubias Barteri reaches about 35 cm tall by 25 cm wide and is usually attached / wedged to hardscape with no substrate required. 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 line-of-sight breaks, spawning sites, grazing surfaces, and shrimp refuge. Place it where Swordtail can actually use that structure instead of hiding the plant where it cannot do much.

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

The decision should center on layout quality: keep the plant in the zone where Swordtail actually swims, shelters, or uses cover.
