Reviewed by Guidarium Editorial DeskUpdated April 28, 2026
Not Recommended

Scarlet Temple is not recommended for Banded Archerfish (Brackish). The issue is practical, not cosmetic: their hardness ranges are too far apart for a reliable long-term match.

Quick Decision

A plant can be technically compatible with a fish and still fail in the actual tank if the fish digs, chews, needs denser cover, or uses a different part of the layout.

Overall fit

60/100

The fish is likely to outgrow, uproot, or out-pressure the plant.

Water match

Limited overlap

One or more core water ranges does not overlap cleanly.

Plant pressure

Low

Banded Archerfish (Brackish) is not flagged as unusually hard on this plant.

Layout value

Moderate cover

Scarlet Temple helps with breaks lines of sight, good refuge for fry, and good refuge for shrimp.

Shared Tank Conditions

Scarlet Temple 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: Scarlet Temple is listed for freshwater, while Banded Archerfish (Brackish) is listed for brackish water.

Fish Pressure and Plant Resilience

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

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

Layout Fit

Scarlet Temple is a stem 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.

Scarlet Temple reaches about 45 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 line-of-sight breaks, fry refuge, and shrimp refuge. Place it where Banded Archerfish (Brackish) can actually use that structure instead of hiding the plant where it cannot do much.

Practical Recommendation

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.

Best Use Case

Scarlet Temple 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.
