Is Water Primrose a Good Plant for Electric Blue Hap?
Water Primrose is not recommended for Electric Blue Hap. The issue is practical, not cosmetic: their pH ranges do not line up well enough for one stable setup.
Water Primrose
Ludwigia palustris
Electric Blue Hap
Sciaenochromis fryeri
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.
82/100
The fish is likely to outgrow, uproot, or out-pressure the plant.
Limited overlap
One or more core water ranges does not overlap cleanly.
Low
Electric Blue Hap is not flagged as unusually hard on this plant.
Moderate cover
Water Primrose helps with breaks lines of sight and good refuge for fry.

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 No clean overlap.
Overlap: 10-15 dGH.
Flow expectations are close enough for one layout.
Plant pressure: Low.
Shared Tank Conditions
Water Primrose and Electric Blue Hap 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
Electric Blue Hap does not put unusual pressure on this plant compared with harder fish-plant combinations.
Water Primrose has moderate cover density, moderate uproot resistance, and standard leaves. It can also help with breaking up sight lines and fry refuge.
The plant helps break up sight lines, which can soften territorial behaviour.
The limiting issue is their pH ranges do not line up well enough for one stable setup.
Layout Fit
Water Primrose is a stem plant usually used midground and background.
Electric Blue Hap is an African cichlid, so the pairing works best when the planting style supports how that fish uses space and cover.
Water Primrose reaches about 40 cm tall by 10 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 fry refuge. Place it where Electric Blue Hap 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.
