They also share practical benefits such as fry refuge and 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 fry and good refuge for shrimp.

Choose Gratiola 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.

Gratiola makes more sense in lower-light scapes.

Gratiola gives you more propagation flexibility through stem cuttings and side shoots / offsets.

Gratiola also suits keepers who want moderate light and recommended added CO2, with fast growth, moderate maintenance, and intermediate difficulty.

HC Cuba / Dwarf Baby Tears is the tidier fit when space is limited.

HC Cuba / Dwarf Baby Tears fits a routine built around high light and required added CO2, with moderate growth, high maintenance, and intermediate difficulty.

Role overlap lands at 22/100 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.

Gratiola is rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a mixed feeder. HC Cuba / Dwarf Baby Tears is rooted in substrate with nutrient-rich substrate required and feeds mainly as a mixed 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.

Do not buy them as interchangeable plants. Use this comparison to decide which tradeoff matters less in your tank: care demand, mature size, placement, or visual density.

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.

Gratiola and HC Cuba / Dwarf Baby Tears overlap enough to invite comparison, but they stop being interchangeable once your tank goals become specific. The main tradeoff is whether you want the plant that better fits your present setup, or the one that only pays off after you change light, feeding, or maintenance habits.
