Can Congo Anubias and Green Lily Grow Together?

Congo Anubias and Green Lily share a workable water window around 22 to 28 °C, pH 6 to 7.5, and 3 to 12 dGH.

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

Flow is workable if the layout gives Congo Anubias moderate flow and Green Lily gentle, low-flow water.

Their light and CO2 needs are close enough for one routine: Congo Anubias does best with low light and no added CO2, while Green Lily does best with moderate light and optional 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.

Congo Anubias reaches about 50 cm tall by 30 cm wide, while Green Lily reaches about 35 cm tall by 25 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.

Congo Anubias is typically roots anchored, rhizome exposed with no substrate required and feeds mainly as a water column feeder. Green Lily 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.

They can share the space, but the scape will stay cleaner if you leave more room than the labels alone might suggest.

Congo Anubias brings slow growth, low maintenance, and beginner difficulty. Green Lily brings moderate growth, moderate maintenance, and beginner 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 you will want to leave more room than usual for mature spread and routine thinning; 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.

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 are willing to manage the scape, not when you want a plant-and-forget combination. Start with more spacing than you think you need, then adjust once both plants show their real growth pace.

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.

This pairing is best treated as a layout decision, not just a water-parameter match. Congo Anubias and Green Lily can work together, but only when you intentionally manage spacing, shade, and maintenance so the stronger grower does not quietly turn the other into dead weight.
