Plant comparison
Glossostigma vs Monte Carlo
How the Glossostigma and Monte Carlo compare on care, size, water and temperament, and which plant suits your tank.
By Mike ElmiraUpdated
TL;DR, Glossostigma vs Monte Carlo
The Glossostigma and the Monte Carlo come up together a lot when people are choosing a plant, and they are close enough to weigh side by side. Both are happy somewhere around 20 to 26 °C and pH 6 to 7, so a single tank can suit either one. The Monte Carlo is the more forgiving of the two, which matters if this is an early tank, while the Glossostigma rewards a bit more attention. Read the full care notes on each below and pick the one whose look and pace fit the tank you're building.
