But I think they mean golden fish or Ikan Mas and speaking about fish, Ikan Mas or golden fish is always serve at Sundanese dish, it is a must that's why very Sundanese Restos have it on their menu list- go check.:-) We like Ikan Mas Bakar/grilled golden fish, Ikan Mas Goreng/fried golden fish or Pepes Ikan (fish steamed with traditional ingredients and wrapped with banana leaves- I might share the recipe later for you!;-))
