Can Buce Motleyana and Quillwort Grow Together?

Buce Motleyana and Quillwort share a workable water window around 20 to 24 °C, pH 5.5 to 7.5, and 2 to 8 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.

Their light and CO2 needs are close enough for one routine: Buce Motleyana does best with low light and optional added CO2, while Quillwort does best with moderate light and optional added CO2.

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

Buce Motleyana reaches about 10 cm tall by 15 cm wide, while Quillwort reaches about 15 cm tall by 10 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.

Buce Motleyana is typically attached / wedged to hardscape with no substrate required and feeds mainly as a water column feeder. Quillwort is typically rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a root feeder. That difference can make the pairing easier to arrange than two plants fighting for the exact same root or attachment zone.

Mature size is not the main thing working against this pairing, so normal maintenance is usually enough to keep the scape readable.

Buce Motleyana brings slow growth, low maintenance, and beginner difficulty. Quillwort brings slow growth, low maintenance, and intermediate difficulty. If one grows much faster, trim that plant before it starts making the other look like the problem.

The practical watch-outs are that both plants tend to work in the foreground and midground, so spacing matters more than usual; and that their substrate preferences are different enough that rooted nutrition should be planned deliberately.

The strongest reasons to try the mix are that they share a workable temperature window around 20 to 24 °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.
