The Spotted Rasbora (Boraras maculatus) is a diminutive and endearing micro fish native to slow-moving, heavily vegetated peat swamp streams and forest pools in Peninsular Malaysia and Sumatra. Reaching only about 2.5 cm in length, it has a semi-translucent pinkish to reddish body adorned with a series of bold black spots along the flank, giving it a uniquely spotted appearance among the Boraras genus. It closely resembles Boraras brigittae but is distinguished by its spotted rather than stripe-and-spot patterning. In the wild, it inhabits the same type of tannin-stained, soft, and acidic blackwater habitat typical of the Boraras family. These conditions should be replicated in the aquarium with soft water, low pH, dim lighting, and a natural leaf litter or dark substrate. A heavily planted nano aquarium with Indian almond leaves and driftwood creates an ideal biotope. As with other micro rasboras, the Spotted Rasbora should be kept in groups of at least eight for comfort and natural behavior. Larger groups of twelve or more produce a lively, shimmering mass of color and movement. It is fully compatible with dwarf shrimp such as Neocaridina and Caridina, making it one of the few fish suitable for a shrimp-focused aquarium. It will not harm adult shrimp or larger juveniles. Diet consists of micro-sized foods including baby brine shrimp, micro worms, daphnia, and crushed flake or micro-pellets.
