TL;DR, Alternanthera Reineckii 'Mini' vs Monte Carlo
The Alternanthera Reineckii 'Mini' 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 22 to 26 °C and pH 6 to 7.5, so a single tank can suit either one. Neither is harder than the other to keep, so the choice comes down to look and stocking rather than skill. Read the full care notes on each below and pick the one whose look and pace fit the tank you're building.
