Is Anubias Barteri a Good Plant for Gardner's Killifish?

Anubias Barteri 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: Anubias Barteri 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.

Gardner's Killifish does not put unusual pressure on this plant compared with harder fish-plant combinations.

Anubias Barteri has moderate cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines, spawning sites, grazing surfaces, and shrimp 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.

Anubias Barteri is a rhizome / epiphyte plant usually used midground, background, and attached to hardscape.

Gardner's Killifish is a killifish, so the pairing works best when the planting style supports how that fish uses space and cover.

Anubias Barteri reaches about 35 cm tall by 25 cm wide and is usually attached / wedged to hardscape 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 line-of-sight breaks, spawning sites, grazing surfaces, and shrimp refuge. Place it where Gardner's Killifish can actually use that structure instead of hiding the plant where it cannot do much.

Treat this as a managed pairing. Plant it securely, give it time to root or attach, and use other plants or hardscape if the fish needs more shelter than one species can provide.

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.

Anubias Barteri can work with Gardner's Killifish, but only if you are honest about the pressure the fish puts on the layout. This is the kind of pairing that succeeds when the plant is chosen for a reason, protected by placement, and supported by a maintenance routine that anticipates damage or crowding.
