Can Mauritius Micro Sword and Red Mangrove Grow Together?

Mauritius Micro Sword and Red Mangrove share a workable water window around 22 to 28 °C, pH 7 to 7.5, and 10 to 15 dGH.

Mauritius Micro Sword is listed for freshwater, while Red Mangrove 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.

Their light and CO2 needs are close enough for one routine: Mauritius Micro Sword does best with moderate light and optional added CO2, while Red Mangrove does best with high light and no added CO2.

They naturally settle into different parts of the scape, which gives you more room to use each species for what it does best instead of forcing direct competition.

Mauritius Micro Sword reaches about 10 cm tall by 15 cm wide, while Red Mangrove reaches about 120 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.

Both are typically rooted in substrate with nutrient-rich substrate preferred and feed mainly as root feeders. The method is simple, but it also means the same planting zone can feel crowded if they are placed too close together.

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

Mauritius Micro Sword brings slow growth, moderate maintenance, and intermediate difficulty. Red Mangrove brings slow 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 main watch-out is that the layout needs a little thought so one plant does not slowly dim the other.

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.
