Can Slender Anubias and Spade-leaf Anubias Grow Together?

Slender Anubias and Spade-leaf Anubias share a workable water window around 22 to 28 °C, pH 6 to 8, and 2 to 15 dGH.

Both plants are comfortable in freshwater, so salinity is not a meaningful obstacle.

Both prefer moderate flow, so circulation can be planned as one steady pattern.

Both fit low light and no added CO2, so one lighting and CO2 plan can support the pair.

Both plants naturally lean toward the midground, background, and attached to hardscape, which is why spacing, pruning, and final mature size matter more than they do in a more staggered planting mix.

Slender Anubias reaches about 40 cm tall by 30 cm wide, while Spade-leaf Anubias reaches about 45 cm tall by 30 cm wide. Use those mature sizes for the layout, not the small nursery portions you bring home.

Shade is not the main concern here, which makes the layout easier to keep balanced over time.

Both are typically attached / wedged to hardscape with no substrate required and feed mainly as water column feeders. The method is simple, but it also means the same planting zone can feel crowded if they are placed too close together.

Crowding becomes likely once both plants hit mature size, so this pairing really wants a roomier footprint or a more aggressive trim schedule.

Both plants have slow growth, low maintenance, and beginner difficulty. That makes the maintenance rhythm predictable: watch for crowding, remove old leaves, and avoid letting one clump shade the other for weeks at a time.

The practical watch-outs are that both plants tend to work in the midground, background, and attached to hardscape, so spacing matters more than usual; and that their mature spread can crowd the same zone quickly unless the layout is oversized from the start.

The strongest reasons to try the mix are that they share a workable temperature window around 22 to 28 °C; and that their flow preferences sit close enough to tune one layout around both plants.

Use this pairing when you want two plants that can share one routine without forcing a compromise at every step. It is strongest in tanks where mature spacing is planned before the plants fill in.

The simple success test is whether both plants still look healthy after the faster grower has been trimmed several times. If one keeps declining after routine care, the layout is probably asking too much of it.
