This is the first time I have come across this type of fish. What's the name - Tiger Fish. The seller also told us its flesh is soft and taste very good. A check in the internet, I found many species other than this!
Out in the restaurants, the price for this size would probably cost RM60 - 70 based on the price we paid in the wet market. It has a very heavy weight for a medium size fish like that though.
Certainly to taste the freshness of the fish (flesh), the better way to cook it is steamed. We prefer it steamed with soy sauce.
