Can Gillet's Anubias and Madagascar Lace Plant Grow Together?

Gillet's Anubias and Madagascar Lace Plant share a workable water window around 22 to 24 °C, pH 6 to 7.5, and 4 to 12 dGH.

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

Flow is workable if the layout gives Gillet's Anubias moderate flow and Madagascar Lace Plant strong, stream-style flow.

Their light and CO2 needs are close enough for one routine: Gillet's Anubias does best with low light and no added CO2, while Madagascar Lace Plant does best with moderate light and recommended added CO2.

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

Gillet's Anubias reaches about 40 cm tall by 30 cm wide, while Madagascar Lace Plant reaches about 60 cm tall by 40 cm wide. Use those mature sizes for the layout, not the small nursery portions you bring home.

Shade is worth watching, but it is usually manageable through trimming and a little spatial separation.

Gillet's Anubias is typically attached / wedged to hardscape with no substrate required and feeds mainly as a water column feeder. Madagascar Lace Plant is typically bulb / tuber on or partly 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.

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

Gillet's Anubias brings slow growth, low maintenance, and beginner difficulty. Madagascar Lace Plant brings moderate growth, high maintenance, and advanced 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 their nutrient appetites are far enough apart that dosing will need a closer eye; and that both plants tend to work in the midground and background, 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; and that the layout needs a little thought so one plant does not slowly dim the other; and that their substrate preferences are different enough that rooted nutrition should be planned deliberately; and that growth pace and maintenance rhythm are uneven, so the stronger grower can dominate if pruning slips.

The strongest reasons to try the mix are that they share a workable temperature window around 22 to 24 °C; and that their flow preferences sit close enough to tune one layout around both plants.

Skip this pairing for most display tanks unless you have a specific reason to experiment. A better long-term choice is a partner plant that shares the same water window and asks for less compromise in light, flow, or maintenance.

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.

Gillet's Anubias and Madagascar Lace Plant are usually better used in separate scapes built around different goals. The practical problem is not that one of them is a bad plant; it is that their long-term maintenance rhythm, spacing, or environmental preferences pull the layout in different directions.
