Shared Tank Conditions

Uruguay Sword fits inside the water range normally used for Peter's Elephantnose Fish. The shared window is about 23 to 28 °C, pH 6 to 7.5, 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.

Fish Pressure and Plant Resilience

Peter's Elephantnose Fish does not put unusual pressure on this plant compared with harder fish-plant combinations.

Uruguay Sword has moderate cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines and spawning sites.

It gives Peter's Elephantnose Fish useful visual shelter and line-of-sight breaks.

The point to watch is this plant can darken the layout more than ideal for fish that prefer lighter plant cover.

Layout Fit

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

Peter's Elephantnose Fish is an oddball fish, so the pairing works best when the planting style supports how that fish uses space and cover.

Uruguay Sword reaches about 55 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 and spawning sites. Place it where Peter's Elephantnose Fish can actually use that structure instead of hiding the plant where it cannot do much.

Practical Recommendation

This is a sensible planted-tank choice for Peter's Elephantnose Fish, 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: This plant can darken the layout more than ideal for fish that prefer lighter plant cover.

Best Use Case

Uruguay Sword is a strong choice for Peter's Elephantnose Fish 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.
