Is Floating Fern a Good Plant for Pink Tailed Chalceus?

Floating Fern fits inside the water range normally used for Pink Tailed Chalceus. The shared window is about 23 to 28 °C, pH 6 to 7.5, and 5 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.

Flow is another friction point because Floating Fern prefers gentle, low-flow water while Pink Tailed Chalceus prefers strong, stream-style flow.

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

Pink Tailed Chalceus does not put unusual pressure on this plant compared with harder fish-plant combinations.

Floating Fern has high cover density, low uproot resistance, and standard leaves. It can also help with surface cover, fry refuge, shrimp refuge, grazing surfaces, and breaking up sight lines.

It directly supplies the floating cover Pink Tailed Chalceus tends to use.

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

Floating Fern is a floating plant usually used floating.

Pink Tailed Chalceus is a characin, so the pairing works best when the planting style supports how that fish uses space and cover.

Floating Fern reaches about 3 cm tall by 5 cm wide and is usually free-floating with no substrate required. 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 surface cover, fry refuge, shrimp refuge, grazing surfaces, and line-of-sight breaks. Place it where Pink Tailed Chalceus 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.

Floating Fern is usually the wrong plant for Pink Tailed Chalceus 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.
