Where seen? This
large colourful fish is often seen in groups in our mangroves at Sungei
Buloh Wetland Reserve and Pasir Ris. The fish is native to India and
Sri Lanka and was introduced to Singapore, possibly through the aquarium
trade. It has since escaped and are now breeding in our waters.
Features: Up to 30cm, usually
about 20cm long. Oval with a short snout and small mouth. Greyish
green with 6 to 8 dark bars, a dark spot at the base of the pectoral
fins, many scales with a pearly spot. It is sometimes called the Pearlspot. |

What does it eat? It is mainly
herbivorous feeding on filamentous algae, plant material. It may also
eat insects. At Sungei Buloh, often seen nibbling on jetty legs and
mangrove roots.
Baby chromides: Several adults
may take care of a single brood that presumably were spawned by only
two of the adults. Tan Heok Hui and Lionel Ng Chin Soon observed a pair with a shoal of fry in Sentosa, suggesting that the fishes have adapted to more marine conditions and may spread among our Southern shores, potentially displacing native species that occupy the same niche.
Human uses: Elsewhere, it is raised
in aquaculture and also in the aquarium trade. |
