Is Willisii a Good Plant for Peacock Bass Temensis?

Willisii fits inside the water range normally used for Peacock Bass Temensis. The shared window is about 26 to 28 °C, pH 6 to 7.5, and 4 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.

Flow is another friction point because Willisii prefers gentle, low-flow water while Peacock Bass Temensis prefers strong, stream-style flow.

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

Peacock Bass Temensis does not put unusual pressure on this plant compared with harder fish-plant combinations.

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.

Its structure adds useful refuge value beyond the normal visual role of the plant.

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

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

Peacock Bass Temensis is a South American cichlid, 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 Bass Temensis 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.

Willisii is usually the wrong plant for Peacock Bass Temensis 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.
