Cuphea anagalloidea is a relatively rare aquarium stem plant from Brazil that became popular in aquascaping because of its unusual colouring and compact growth. It was originally circulated in the hobby under the name “Rotala sp. Araguaia” before being correctly identified as a Cuphea species.
It has small, narrow oval leaves on upright stems. Under strong lighting and good CO₂ levels, the leaves develop orange, red and scarlet tones, often with tiny green speckles. In lower light, it tends to stay greener and loses much of its colour intensity.
In aquariums it is usually used as a midground accent plant, especially in Dutch-style layouts where its upright, bushy form creates contrast against broader-leaved species. Regular trimming encourages denser growth and allows it to be shaped into neat groups.
Care level is generally considered difficult. It performs best with:
* High light
* Added CO₂
* Regular fertilisation
* Soft, slightly acidic water
* Stable water conditions
Without those conditions it often grows slowly, loses colour or becomes leggy.
For many aquascapers, the appeal is that it offers red and orange tones that look different from common plants like Rotala rotundifolia or Ludwigia repens, making it a standout feature in a planted tank.
