Can Baby Tears and Micro Sword Grow Together?

Baby Tears and Micro Sword share a workable water window around 20 to 28 °C, pH 6 to 7.5, and 2 to 15 dGH.

Baby Tears is listed for freshwater, while Micro Sword 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: Baby Tears does best with moderate light and optional added CO2, while Micro Sword does best with moderate light and recommended 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.

Baby Tears reaches about 30 cm tall by 15 cm wide, while Micro Sword reaches about 7 cm tall by 15 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.

Baby Tears is typically rooted in substrate with inert substrate is fine and feeds mainly as a mixed feeder. Micro Sword 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.

Baby Tears brings fast growth, moderate maintenance, and beginner difficulty. Micro Sword brings slow growth, moderate maintenance, and intermediate 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 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 20 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.
