Is Mexican Oak Leaf a Good Plant for Duplicareus Corydoras?

Mexican Oak Leaf fits inside the water range normally used for Duplicareus Corydoras. The shared window is about 22 to 26 °C, pH 6 to 7.2, and 2 to 12 dGH, which gives you enough room to aim for stable middle-ground conditions.

Both do best with moderate flow, 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.

Duplicareus Corydoras puts heavy pressure on plants, so this species is likely to be chewed, uprooted, or stressed in day-to-day use.

Mexican Oak Leaf has moderate cover density, low uproot resistance, and standard leaves. It can also help with breaking up sight lines, fry refuge, and surface cover.

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

The limiting issue is duplicareus Corydoras is likely to uproot this plant while digging through the substrate.

Mexican Oak Leaf is a stem plant usually used midground and background.

Duplicareus Corydoras is a catfish, so the pairing works best when the planting style supports how that fish uses space and cover.

Mexican Oak Leaf reaches about 60 cm tall by 15 cm wide and is usually rooted in substrate with inert substrate is fine. 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, fry refuge, and surface cover. Place it where Duplicareus Corydoras 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: Duplicareus Corydoras is likely to uproot this plant while digging through the substrate.

Mexican Oak Leaf is usually the wrong plant for Duplicareus Corydoras 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.
