Sometimes shoals of the young, with reddish stripes along the body can be seen swimming around with the parents close by

Economic
Importance              In fresh form the demand is not very good. Formally the market price was only RM2.0- RM3.00 per kg. In its dried form they have good export potential, and fetch between RM8.00 - RM10.00. Now the fresh fish fetches quite a high prices as they are exported to Singapore.
