Plectorhinchus gaterinus, also know as Blackspotted rubberlips, are often found near sandbars and river estuaries but also in the nearby coastal reefs along the east coast of Africa. From the Red Sea through Kenya and Mozambique as well as Somalia, south to the coast of South Africa (Republic), and east to Madagascar.
The Blackspotted rubberlips shows a silver base color with a yellow belly and fins, and the name presentive black spots all over his body which continue in the back and tail fin. The pectoral fins are yellow, the front part of the head usually gray-blue. As juveniles the basic color is the same but instead of points you can see them with black stripes which „dissolve“ with age on dots.
Juvenils are usually found single and hiding between corals whereas adults are often seen in large groups or swarms. They feed on both sessile (fixed) and vagile (freely movable), benthic invertebrates, practically every living organisms that stays near the ground.
