Spotted Rasbora (Boraras maculatus)
Size and Lifespan
These fish grow to just 2 cm, ideal for small tanks. Additionally, they live around 3–5 years with proper care. Their petite size and active schooling behavior enhance nano setups. Therefore, maintaining stable water conditions ensures their health and vibrant coloration.
Ideal Tank Setup
Create a nano tank with dense plants and gentle water flow to mimic their habitat. A 20-liter tank offers ample space for schooling. Furthermore, subdued lighting and soft, acidic water boost their red hues. To replicate their natural habitat:
- Add fine-leaved plants for cover and spawning.
- Use driftwood to enhance natural aesthetics.
- Choose a dark substrate to highlight colors.
- Install a gentle filter for calm water flow.
Compatible Tank Mates
These peaceful nano fish thrive with other non-aggressive species. Their schooling nature shines in groups of six or more. However, avoid larger or aggressive fish to ensure their safety. Suitable tank mates include:
- Pygmy Corydoras
- Ember Tetras
- Cherry Shrimp
- Small Rasboras
Diet and Feeding
These micro-predators eagerly eat micro-pellets and crushed flakes. Additionally, they love live or frozen foods like brine shrimp or daphnia. Feed small portions 2–3 times daily, ensuring they finish within 3 minutes. Alternatively, if feeding once daily, offer what they can eat in 5 minutes to avoid waste.
Breeding and Behaviour of Maculata Dwarf Spotted Red Rasbora
These fish actively school, adding dynamic movement to tanks. As egg-layers, they need fine-leaved plants for spawning. Moreover, males fertilize scattered eggs, which hatch in 24–36 hours. After spawning, remove adults to protect eggs. Consequently, fry thrive on infusoria or crushed fry food.
