Rosy Barb
Pethia conchonius
About
The rosy barb is a larger, hardy Pethia species from South Asia, tolerating cooler water than many tropical fish—useful for unheated indoor tanks in mild climates. Males develop pink-red breeding colour; females are heavier-bodied. Active mid-water swimmers that appreciate a long tank and a group of six or more. They may browse soft algae and benefit from vegetable matter in the diet. Egg scatterers with no brood care; can grow sizeable in aquaria—plan tank volume accordingly.
