Alternanthera reineckii 'Mini' is a compact, lower-growing form of the popular AR that stays more manageable in smaller planted tanks. The deep burgundy-red foliage creates strong visual contrast against surrounding green plants.
It performs best under medium to bright lighting with CO2 supplementation, which intensifies the red tones and promotes bushy growth. Under lower conditions the colour fades and the stems become leggy, so it rewards a well-equipped setup. That said, it's more accessible than many demanding red plants, making it a good step up for aquascapers moving on from beginner species.
Trim regularly to keep the growth compact and encourage branching. Plant in small groups in the foreground or midground.
