Aquarium Care (Advanced Level Only)
Due to its specialized care needs, L. aura is not typically recommended for beginners. In captivity, it thrives in species-only, mature setups that replicate its natural habitat—soft, acidic water (pH 4.5–6.5), gentle currents, low lighting, dark substrates, dense plants, floating vegetation, and peat or driftwood to mimic tannin-stained water. It requires live or frozen foods and should be kept in small, similarly sized groups to minimize territorial conflicts .
