Diet

Micropredatory omnivore: finely crushed quality flakes or micro-pellets, plus tiny live/frozen foods such as baby brine shrimp, daphnia, cyclops, microworms, and finely sized bloodworm

Community Compatibility

Peaceful shoaling nano fish; keep at least 8–10, ideally 15+ in a planted tank. Best with similarly tiny, calm fish and invertebrates; avoid large, fast, or boisterous tankmates that may intimidate or outcompete them for food

Good to Know

Despite reaching barely 2.5 cm (1 inch), Dwarf Spotted Rasboras can transform a leaf-littered blackwater aquarium into a moving cloud of tiny red-orange sparks.

Gender Differences

Males are generally slimmer, smaller-looking, and show stronger orange-red to red colouration—especially when displaying. Females are usually slightly larger, less intensely coloured, and noticeably rounder through the belly when mature or carrying eggs.
