Maculata Rasbora

Overview

The Dwarf Spotted Rasbora (Boraras maculatus) is one of the smallest aquarium fish, reaching only about 2–2.5 cm. It has a warm salmon-to-red body marked with bold dark spots on the flank and at the base of the fins. It comes from blackwater peat-swamp streams in Malaysia and Sumatra and looks its best in a densely planted nano tank.

Water Parameters

• Temperature: 24–28°C (75–82°F)
• pH: 5.0–7.0
• Hardness: 1–8 dGH (soft water preferred)

Tank Setup

• Minimum tank size: 20 litres for a group of 8–10; larger groups need more space
• Decor: Dense planting, floating plants, leaf litter, dim to moderate lighting and very gentle flow

Diet

• Base: Micro flake, crushed granules, nano pellets
• Treats: Baby brine shrimp, micro worms, crushed daphnia

Temperament & Tank Mates

• Temperament: Peaceful, shy schooling fish
• Best companions: Other nano fish (Strawberry or Chili Rasboras, Ember Tetras), dwarf shrimp, small snails
• Schooling: Minimum 8–10

Common Issues

• Very small — easily outcompeted for food by larger fish
• Colours fade in hard water or bright, bare tanks
• Feed small portions often; uneaten food fouls nano tanks quickly
