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

56/100

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

Moderate

Scarlet Temple needs thoughtful placement and anchoring.

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 Violet Goby (Dragon Goby) 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 Violet Goby (Dragon Goby) is listed for brackish water.

Fish Pressure and Plant Resilience

Violet Goby (Dragon Goby) 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.

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.

It gives Violet Goby (Dragon Goby) useful visual shelter and line-of-sight breaks.

The limiting issue is they are adapted to different water types.

Layout Fit

Scarlet Temple is a stem plant usually used midground and background.

Violet Goby (Dragon Goby) is a goby or gudgeon, 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 Violet Goby (Dragon Goby) 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: They are adapted to different water types.

Best Use Case

Scarlet Temple is usually the wrong plant for Violet Goby (Dragon Goby) 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.
