Is Watermeal a Good Plant for Festivum?
Watermeal is not recommended for Festivum. The issue is practical, not cosmetic: festivum is likely to chew or tear this plant before it settles in.

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.
68/100
The fish is likely to outgrow, uproot, or out-pressure the plant.
Workable overlap
Shared range: 24-28°C, pH 5.5-7.2, 2-12 dGH.
High
Festivum may chew, uproot, or stress this plant.
High cover
Watermeal helps with provides surface cover and good grazing surface.

Plant and Fish Fit Notes
Use these signals to decide whether the plant is doing useful work for the fish, or whether it is only surviving beside it.
Overlap: 24-28°C.
Overlap: pH 5.5-7.2.
Overlap: 2-12 dGH.
Flow expectations are close enough for one layout.
Plant pressure: High.
Shared Tank Conditions
Watermeal fits inside the water range normally used for Festivum. The shared window is about 24 to 28 °C, pH 5.5 to 7.2, and 2 to 12 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.
Fish Pressure and Plant Resilience
Festivum puts heavy pressure on plants, so this species is likely to be chewed, uprooted, or stressed in day-to-day use.
Watermeal has high cover density, low uproot resistance, and delicate leaves. It can also help with surface cover and grazing surfaces.
It directly supplies the floating cover Festivum tends to use.
The limiting issue is festivum is likely to chew or tear this plant before it settles in.
Layout Fit
Watermeal is a floating plant usually used floating.
Festivum is a South American cichlid, so the pairing works best when the planting style supports how that fish uses space and cover.
Watermeal reaches about 0.1 cm tall by 0.1 cm wide and is usually free-floating with no substrate required. 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 surface cover and grazing surfaces. Place it where Festivum 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: Festivum is likely to chew or tear this plant before it settles in.
