Quick Decision

A plant can be technically compatible with a fish and still fail in the actual tank if the fish digs, chews, needs denser cover, or uses a different part of the layout.

Overall fit

66/100

The fish is likely to outgrow, uproot, or out-pressure the plant.

Water match

Limited overlap

One or more core water ranges does not overlap cleanly.

Plant pressure

Moderate

Uruguay Sword needs thoughtful placement and anchoring.

Uruguay Sword helps with breaks lines of sight and useful spawning site.

Shared Tank Conditions

Uruguay Sword and Orange Peacock do not share a clean environmental window, so the pairing is already under pressure before behaviour is even considered.

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

Orange Peacock 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.

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.

Uruguay Sword brings useful structure to the tank instead of serving only as decoration.

The limiting issue is their pH ranges do not line up well enough for one stable setup.

Layout Fit

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

Orange Peacock is an African cichlid, 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 Orange Peacock can actually use that structure instead of hiding the plant where it cannot do much.

Practical Recommendation

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: Their pH ranges do not line up well enough for one stable setup.

Best Use Case

Uruguay Sword is usually the wrong plant for Orange Peacock 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.
