The yellowbar angel fish Pomacanthus maculosus (Forsskål)
(Perciformes: Pomacanthidae) is a beautiful, omnivorous, coral reef
fish distributed throughout the Arabian Gulf, the northwestern Indian
Ocean and the Red Sea, which mainly feeds on algae, sponges and
encrusting invertebrates [1 –4]. Owing to its striking colour patterns, P.
maculosus is also a marine ornamental fish with very important commercial value [5].
