Is Radican Sword a Good Plant for Dwarf Pea Puffer?

Radican Sword fits inside the water range normally used for Dwarf Pea Puffer. The shared window is about 22 to 28 °C, pH 6.5 to 7.5, and 4 to 15 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.

Dwarf Pea Puffer 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.

This plant adds the denser cover that Dwarf Pea Puffer usually appreciates.

There is no special plant-pressure warning here, so solid anchoring and stable husbandry matter more than unusual protection.

Radican Sword is a rosette / crown plant usually used midground and background.

Dwarf Pea Puffer is a puffer, 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 Dwarf Pea Puffer can actually use that structure instead of hiding the plant where it cannot do much.

This is a sensible planted-tank choice for Dwarf Pea Puffer, especially when you want the plant to do real work as cover, sight-line structure, or habitat detail.

The decision should center on layout quality: keep the plant in the zone where Dwarf Pea Puffer actually swims, shelters, or uses cover.
