Care notes
An aquarium of at least 40 liters is sufficient for a small group. Water should be soft (GH 5-12), acidic to neutral (pH 6.0-7.5) and kept between 24-28°C. Gentle filtration and moderate lighting are suitable. Plant densely while leaving swimming spaces. Feed with micro-foods, brine shrimp nauplii and fine flakes. Weekly 20% water changes are recommended. Avoid large or aggressive tankmates.
