This SKU is currently out of stock locally when inventory shows zero, but the care advice remains here so you can plan a suitable livebearer aquarium before new stock is available.
Use quality flakes, micro pellets, spirulina foods, blanched greens and occasional frozen foods such as daphnia or brine shrimp. A vegetable-rich diet helps digestion and condition.
