Swimming zone and behavior

This fish uses the bottom area, so leave enough open substrate area for movement and feeding.

Feeding

Use a varied routine that suits a plant-leaning or algae-focused diet.

Make sure food reaches the substrate before faster fish take it.

The aquarium must produce natural diatoms, algae and biofilm. Supplement with spirulina, algae-based foods and very small invertebrate foods, but do not rely on wafers alone.

Natural habitat and origin

Natural habitat: Clear, highly oxygenated coastal streams in Japan, Taiwan, southern China, the Philippines and Malaysia. Adults graze epiphytes and biofilm from rock; the life cycle is amphidromous.

Breeding notes

Breeding difficulty: Not practical in standard freshwater aquariums.

The species reaches about 5 cm total length. Larvae naturally drift to marine or brackish water before juveniles migrate upstream, which makes home breeding exceptionally difficult. Wild collection can add pressure to local populations.

Before adding this fish

• Plan for an aquarium of 54 L or larger / ≥ 60 cm (≥ 23.6 in) minimum length.
• Avoid aggressive or highly competitive fish.
• Offer a varied diet that matches this species.
