Is Water Violet a Good Plant for Gardner's Killifish?
Water Violet is a strong fit for Gardner's Killifish. The shared water window is realistic, and the plant has enough structure or resilience to be useful in a tank built around this fish. Fish pressure is low, so the plant can be judged mostly on water match, cover value, and layout role.

Hottonia palustris
Gardner's Killifish
Fundulopanchax gardneri
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.
84/100
The plant and fish suit each other well.
Workable overlap
Shared range: 20-26°C, pH 6-7.5, 4-10 dGH.
Low
Gardner's Killifish is not flagged as unusually hard on this plant.
High cover

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: 20-26°C.
Overlap: pH 6-7.5.
Overlap: 4-10 dGH.
Flow expectations are close enough for one layout.
Plant pressure: Low.
Shared Tank Conditions
Water Violet fits inside the water range normally used for Gardner's Killifish. The shared window is about 20 to 26 °C, pH 6 to 7.5, and 4 to 10 dGH, which gives you enough room to aim for stable middle-ground conditions.
Their flow expectations are close enough to combine: Water Violet prefers moderate flow, while Gardner's Killifish prefers gentle, low-flow water.
Both are suited to freshwater, so salinity does not add an extra planning problem.
Fish Pressure and Plant Resilience
Gardner's Killifish does not put unusual pressure on this plant compared with harder fish-plant combinations.
Water Violet has high cover density, low uproot resistance, and delicate leaves. It can also help with breaking up sight lines, shrimp refuge, and fry refuge.
This plant adds the denser cover that Gardner's Killifish usually appreciates.
The point to watch is gardner's Killifish often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.
Layout Fit
Water Violet is a stem plant usually used midground and background.
Gardner's Killifish is a killifish, so the pairing works best when the planting style supports how that fish uses space and cover.
Water Violet reaches about 40 cm tall by 6 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, shrimp refuge, and fry refuge. Place it where Gardner's Killifish 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 Gardner's Killifish, 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: Gardner's Killifish often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.
