Is Radican Sword a Good Plant for Neon Blue Goby?

Radican Sword fits inside the water range normally used for Neon Blue Goby. The shared window is about 22 to 28 °C, pH 6.5 to 7.5, and 4 to 12 dGH, which gives you enough room to aim for stable middle-ground conditions.

Flow is another friction point because Radican Sword prefers gentle, low-flow water while Neon Blue Goby prefers strong, stream-style flow.

Both are suited to freshwater, so salinity does not add an extra planning problem.

Neon Blue 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.

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.

The plant helps break up sight lines, which can soften territorial behaviour.

The limiting issue is the fish wants a very different current pattern than the plant prefers.

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

Neon Blue Goby is a goby or gudgeon, 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 Neon Blue Goby can actually use that structure instead of hiding the plant where it cannot do much.

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: The fish wants a very different current pattern than the plant prefers.

Radican Sword is usually the wrong plant for Neon Blue 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.
