Can Creeping Jenny and Mauritius Micro Sword Grow Together?

Grows Well Together

Yes. Creeping Jenny and Mauritius Micro Sword can grow well together in the right layout. The shared water range is about 15 to 26 °C, pH 6 to 7.5, and 4 to 15 dGH. Their care needs are close enough for one routine, and the main job is practical placement. They use different parts of the scape, which lowers direct space competition.

Quick Decision

Use this first pass to decide whether the pairing deserves a real place in the tank plan before you get into the full care details.

Overall fit

83/100

Shared setup and layout demands are easy to reconcile.

Water match

Workable overlap

Shared range: 15-26°C, pH 6-7.5, 4-15 dGH.

Layout pressure

Low crowding

Creeping Jenny and Mauritius Micro Sword mostly use different scape zones.

Main watch-out

Caution

Growth pace and maintenance rhythm are uneven, so the stronger grower can dominate if pruning slips.

Side-by-Side Planting Notes

The best coexistence pairings are not just plants with similar water ranges. They also need compatible mature size, feeding style, shade, and maintenance rhythm.

Shared Environment

Creeping Jenny and Mauritius Micro Sword share a workable water window around 15 to 26 °C, pH 6 to 7.5, and 4 to 15 dGH.

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

Both prefer moderate flow, so circulation can be planned as one steady pattern.

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

Layout and Spacing

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.

Creeping Jenny reaches about 40 cm tall by 5 cm wide, while Mauritius Micro Sword reaches about 10 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.

Creeping Jenny is typically rooted in substrate with inert substrate is fine and feeds mainly as a water column feeder. Mauritius 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.

Maintenance Outlook

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

Creeping Jenny brings fast growth, moderate maintenance, and beginner difficulty. Mauritius 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 15 to 26 °C; and that their flow preferences sit close enough to tune one layout around both plants.

Practical Recommendation

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.

Frequently Asked Questions About Creeping Jenny and Mauritius Micro Sword

Can Creeping Jenny and Mauritius Micro Sword grow in the same aquarium?

Yes. Creeping Jenny and Mauritius Micro Sword can grow well together in the right layout. The shared water range is about 15 to 26 °C, pH 6 to 7.5, and 4 to 15 dGH. Their care needs are close enough for one routine, and the main job is practical placement. They use different parts of the scape, which lowers direct space competition.

What water conditions suit both Creeping Jenny and Mauritius Micro Sword?

The shared water window is about 15 to 26 °C, pH 6 to 7.5, and 4 to 15 dGH. Keep the tank in the middle of that overlap instead of chasing the outer edge of either plant's tolerance.

Will Creeping Jenny and Mauritius Micro Sword compete for the same space?

Not heavily. They naturally land in different parts of the scape, which lowers direct space competition.

Is light or CO2 the bigger challenge with this pairing?

Neither light nor CO2 is a major divider here compared with most mixed-plant pairings.

What is the main risk when keeping Creeping Jenny with Mauritius Micro Sword?

Growth pace and maintenance rhythm are uneven, so the stronger grower can dominate if pruning slips.
