Is Creeping Jenny a Good Plant for Australian Pearl Arowana?
Creeping Jenny is a strong fit for Australian Pearl Arowana. The shared water window is realistic, and the plant has enough structure or resilience to be useful in a tank built around this fish. The match depends on anchoring and placement more than the water numbers alone.

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.
84/100
The plant and fish suit each other well.
Workable overlap
Shared range: 24-26°C, pH 6-7.5, 4-15 dGH.
Moderate
Creeping Jenny needs thoughtful placement and anchoring.
Moderate cover
Creeping Jenny helps with breaks lines of sight and good refuge for fry.
Plant and Fish Fit Notes
Use these signals to decide whether the plant is doing useful work for the fish, or whether it is only surviving beside it.
Overlap: 24-26°C.
Overlap: pH 6-7.5.
Overlap: 4-15 dGH.
Flow expectations are close enough for one layout.
Plant pressure: Moderate.
Shared Tank Conditions
Creeping Jenny fits inside the water range normally used for Australian Pearl Arowana. The shared window is about 24 to 26 °C, pH 6 to 7.5, and 4 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.
Both are suited to freshwater, so salinity does not add an extra planning problem.
Fish Pressure and Plant Resilience
Australian Pearl Arowana 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.
Creeping Jenny has moderate cover density, low uproot resistance, and standard leaves. It can also help with breaking up sight lines and fry refuge.
The plant helps break up sight lines, which can soften territorial behaviour.
The point to watch is fast, forceful fish movement can be rough on a plant that anchors lightly.
Layout Fit
Creeping Jenny is a stem plant usually used midground and background.
Australian Pearl Arowana is an oddball fish, so the pairing works best when the planting style supports how that fish uses space and cover.
Creeping Jenny reaches about 40 cm tall by 5 cm wide and is usually rooted in substrate with inert substrate is fine. 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 Australian Pearl Arowana can actually use that structure instead of hiding the plant where it cannot do much.
Practical Recommendation
This is a sensible planted-tank choice for Australian Pearl Arowana, 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: Fast, forceful fish movement can be rough on a plant that anchors lightly.
Best Use Case
Creeping Jenny is a strong choice for Australian Pearl Arowana 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.
