Threadfin Rainbowfish - 4cm (Iriatherina werneri) (Live Fish)

Threadfin Rainbowfish (Iriatherina werneri) are elegant, peaceful rainbowfish admired for their delicate, elongated fins and shimmering silver-gold bodies with flashes of blue and yellow. Their graceful swimming behaviour makes them a stunning feature in well-planted community aquariums.

They thrive in well-maintained aquariums with stable water quality, gentle water flow, and plenty of plants alongside open swimming space. Best kept in groups, they display their natural schooling behaviour and males exhibit spectacular fin displays when competing for attention. Feed a varied diet of quality micro pellets, flakes, frozen, and live foods.

Size, colour, pattern, and appearance may vary.
