Micro Sword vs Sivadasan's Crypt

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

Micro Sword is a stolon / runner plant that usually reaches about 7 cm tall by 15 cm wide. Sivadasan's Crypt is a rosette / crown plant that usually reaches about 50 cm tall by 15 cm wide.

They also share practical benefits such as shrimp refuge, so the decision is not only about looks.

The strongest overlap signals are practical: they offer many of the same practical benefits, including good refuge for shrimp.

Choose Micro Sword 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.

Micro Sword is the tidier fit when space is limited.

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

Micro Sword also suits keepers who want moderate light and recommended added CO2, with slow growth, moderate maintenance, and intermediate difficulty.

Choose Sivadasan's Crypt when its shape, mature size, or planting style gives the scape a cleaner finish than forcing Micro Sword into the same role.

Sivadasan's Crypt makes more sense in lower-light scapes.

Sivadasan's Crypt gives you more propagation flexibility through rhizome division and side shoots / offsets.

Sivadasan's Crypt fits a routine built around low light and optional added CO2, with slow growth, low maintenance, and intermediate difficulty.

Role overlap lands at 16/100 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.

Both use rooted in substrate with nutrient-rich substrate preferred and feed mainly as root feeders. That makes care easy to compare, so focus more on leaf mass, mature footprint, and how much visual weight you want.

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.
