The Three-lined Pencilfish is a small shoaling species known from tributaries, backwaters, and swamplands, where the water is sluggish or almost still, and crowded with dense vegetation and an abundance of leaf litter. The water in the native habitat is very soft and acidic, and stained a tea colour from the tannins in the decaying leaves and wood. The home aquarium should be mature, with a dark substrate and background and with plenty of plant cover - both rooted and floating - in order for these peaceful mid-to-top-dwelling fish to feel secure. Filtration should be efficient but water movement gentle. These fish are best maintained in groups of at least 10, and more than this wherever possible. Dominant males may occasionally bicker with one other, but providing there is a good network of hiding places/visual barriers for them to retreat into if necessary, no harm should ensue.
