Is Vesuvius Sword a Good Plant for Banded Archerfish (Brackish)?

Vesuvius Sword and Banded Archerfish (Brackish) do not share a clean environmental window, so the pairing is already under pressure before behaviour is even considered.

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

Water type is a serious mismatch: Vesuvius Sword is listed for freshwater, while Banded Archerfish (Brackish) is listed for brackish water.

Banded Archerfish (Brackish) does not put unusual pressure on this plant compared with harder fish-plant combinations.

Vesuvius Sword has moderate cover density, moderate uproot resistance, and standard leaves. It can also help with breaking up sight lines and fry refuge.

Its structure adds useful refuge value beyond the normal visual role of the plant.

The limiting issue is their hardness ranges are too far apart for a reliable long-term match.

Vesuvius Sword is a stolon / runner plant usually used midground and background.

Banded Archerfish (Brackish) is an oddball fish, so the pairing works best when the planting style supports how that fish uses space and cover.

Vesuvius Sword reaches about 25 cm tall by 10 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 line-of-sight breaks and fry refuge. Place it where Banded Archerfish (Brackish) can actually use that structure instead of hiding the plant where it cannot do much.

For most keepers, a tougher or better-matched plant is the smarter choice. If you still try it, test with a small amount first and be ready to move the plant before it is badly damaged.

The decision should center on this signal: Their hardness ranges are too far apart for a reliable long-term match.

Vesuvius Sword is usually the wrong plant for Banded Archerfish (Brackish) if your goal is a stable display tank. The issue is rarely one dramatic failure on day one; it is the steady mismatch between what the fish does in the scape and what the plant needs to stay attractive long term.
