Size: adults (TL) length at about twenty centimeters (20 cm), even a bit longer
Depth: Usually found at one meter (1 m) of depth, but occur as well up to about four meters (4 m)
Environment: Reef associated. The species occur in very shallow waters at the intertidal zone. Probably they use permanent residences between pebbles or at the terminals of hangs and caves or crevices, densely planted (algae) sunny rocks.
Food: Algae are the almost only food they feed on
Distribution: Mediterranean Sea, Black Sea, south France, Morocco, east Atlantic Ocean
Common name: Rusty blenny, herbivorus blenny
General info: Adults spawn from May to July or (according other records) from April to August and during spawning season ♂♂ have an overall black coloration. It is easy to be misidentified as P. parvicornis, but the two species show differences to the size and the color of their teeth.
Although not important to fish food market, very popular to aquarists, due to its alimentary habits. It is used to control algae growth in Mediterranean marine systems. The way they swim gives the impression of flying and the animals travel some distances.
They require large aquaria, over five hundred liters (500 l) of volume.
