Can Congo Anubias and Dwarf Sagittaria Grow Together?

Congo Anubias and Dwarf Sagittaria share a workable water window around 22 to 28 °C, pH 6 to 8, and 3 to 15 dGH.

Congo Anubias is listed for freshwater, while Dwarf Sagittaria is listed for freshwater to lightly brackish water. Keep the tank in the shared part of those tolerances rather than pushing either plant to an edge.

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, 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 Dwarf Sagittaria reaches about 25 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.

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

Congo Anubias brings slow growth, low maintenance, and beginner difficulty. Dwarf Sagittaria brings fast 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 both plants tend to work in the midground, so spacing matters more than usual; 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 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.
