Is Radican Sword a Good Plant for Marbled Hatchetfish?
Radican Sword is a strong fit for Marbled Hatchetfish. The shared water window is realistic, and the plant has enough structure or resilience to be useful in a tank built around this fish. Fish pressure is low, so the plant can be judged mostly on water match, cover value, and layout role.
Radican Sword
Echinodorus cordifolius
Marbled Hatchetfish
Carnegiella strigata
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.
94/100
The plant and fish suit each other well.
Workable overlap
Shared range: 24-28°C, pH 6-7.5, 2-12 dGH.
Low
Marbled Hatchetfish is not flagged as unusually hard on this plant.
High cover
Radican Sword helps with breaks lines of sight, useful spawning site, provides surface cover, and good grazing surface.
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: 24-28°C.
Overlap: pH 6-7.5.
Overlap: 2-12 dGH.
Flow expectations are close enough for one layout.
Plant pressure: Low.
Shared Tank Conditions
Radican Sword fits inside the water range normally used for Marbled Hatchetfish. The shared window is about 24 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH, which gives you enough room to aim for stable middle-ground conditions.
Both do best with gentle, low-flow water, 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
Marbled Hatchetfish does not put unusual pressure on this plant compared with harder fish-plant combinations.
Radican Sword has high cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines, spawning sites, surface cover, and grazing surfaces.
It gives Marbled Hatchetfish useful visual shelter and line-of-sight breaks.
The point to watch is marbled Hatchetfish often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.
Layout Fit
Radican Sword is a rosette / crown plant usually used midground and background.
Marbled Hatchetfish is a characin, so the pairing works best when the planting style supports how that fish uses space and cover.
Radican Sword reaches about 60 cm tall by 40 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, spawning sites, surface cover, and grazing surfaces. Place it where Marbled Hatchetfish 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 Marbled Hatchetfish, 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: Marbled Hatchetfish often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.
