Is Willisii a Good Plant for Peacock Eel?

Willisii fits inside the water range normally used for Peacock Eel. The shared window is about 23 to 28 °C, pH 6.5 to 7.5, and 5 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.

Peacock Eel 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.

Willisii has moderate cover density, high uproot resistance, and standard leaves. It can also help with shrimp refuge, grazing surfaces, and breaking up sight lines.

This plant adds the denser cover that Peacock Eel usually appreciates.

The point to watch is substrate activity from the fish means this planting style needs extra anchoring at first.

Willisii is a rosette / crown plant usually used foreground and midground.

Peacock Eel is an oddball fish, so the pairing works best when the planting style supports how that fish uses space and cover.

Willisii reaches about 20 cm tall by 15 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 shrimp refuge, grazing surfaces, and line-of-sight breaks. Place it where Peacock Eel can actually use that structure instead of hiding the plant where it cannot do much.

This is a sensible planted-tank choice for Peacock Eel, 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: Substrate activity from the fish means this planting style needs extra anchoring at first.

Willisii is a strong choice for Peacock Eel 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.
