It is found in both marine and brackish or estuarine waters, feeding on smaller fish and possibly crustaceans. Chirocentrus is from the Greek cheir meaning hand and kentron meaning sting. Dorab is from the Arabic language word darrab (ضرّاب)  and the word is probably a corrupted form of durubb (دُرُبّ) the name for goldfish in Arabic.
