African Onion Plant vs Micro Sword

They do not overlap much in exact placement, which is why this comparison is more about adjacent options than true one-for-one replacements.

African Onion Plant is a bulb / tuber plant that usually reaches about 100 cm tall by 30 cm wide. Micro Sword is a stolon / runner plant that usually reaches about 7 cm tall by 15 cm wide.

Their benefit profile differs enough that the better choice depends more heavily on what the rest of the tank needs.

The comparison is still useful because it shows whether you are choosing between two similar plants or two plants that only look related at first glance.

Choose African Onion Plant when its exact growth habit fits the open space you have and you want the finished scape to lean toward its shape, texture, or spread.

African Onion Plant is the easier keep when you want the simpler option.

African Onion Plant gives you more propagation flexibility through bulb / tuber split and side shoots / offsets.

African Onion Plant also suits keepers who want moderate light and no added CO2, with slow growth, low maintenance, and beginner difficulty.

Choose Micro Sword when its shape, mature size, or planting style gives the scape a cleaner finish than forcing African Onion Plant into the same role.

Micro Sword is the tidier fit when space is limited.

Micro Sword gives denser visual cover when fish security matters more.

Micro Sword fits a routine built around moderate light and recommended added CO2, with slow growth, moderate maintenance, and intermediate difficulty.

Role overlap lands at 0/100 and care similarity lands at 76/100. Treat those numbers as a shortcut for the decision, not as a replacement for looking at mature size and placement.

African Onion Plant is bulb / tuber on or partly in substrate with nutrient-rich substrate preferred and feeds mainly as a root feeder. Micro Sword is rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a root feeder.

Their mature height diverges enough that they stop being true one-for-one replacements.

If the tank already has several demanding plants, the easier choice is the one that matches your existing light, CO2, and trimming routine.

If you need a true substitute, keep looking. This pair is more useful as a contrast because the plants ask for different layout decisions once they mature.

A practical way to decide is to imagine the tank six months from now. The better plant is the one that still fits the same space after several trims, not the one that only looks right on planting day.
