The Lesser pipefish or the Nilsson's Pipefish (Syngnathus rostellatus), a fish similar to the greater pipefish, but with no crest above the head. Usually it reaches up to 17 centimeters in length, maximally 18 cm, although in south Wales they are usually not more than 10 cm to 13 cm long. They have a light to dark green-brown color with bar-like markings on the sides (compare the greater pipefish). Lesser pipesfish are found all around the British Isles and as far as the French coast.

[edit] Anatomy

The head has a long, thin, round snout with a small up-turned mouth; the eyes are small and situated well back towards the gill covers; The body is long and thin, covered with bony plates; the dorsal fin situates half way along the body, and pelvics are found below this. The caudal fin is shaped like a fan, and small pectorals are situated behind the gills. The lesser and greater pipefish species differ because one has a crest on the head while one doesn't. However, they are still quite similar: A fully grown lesser pipefish and a young greater pipefish share similar coloration and markings and they both have a caudal fin and swim in a similar style. One distinguishing feature of the lesser pipefish is a continuous black line from the gills down the belly to the tail, although this not very apparent on very young specimens.

[edit] Habits

The lesser pipefish feeds on small crustaceans, and makes its habitat in shallow water. In aquariums, this species should be kept at a temperature no more than 18°C and need to be fed on live food. Breeding takes place in spring and summer. The adult male carries the eggs and young in a brood pouch until they are able enough to fend for themselves. They can carry about 100 eggs. The young will hatch after about 3 weeks and are pelagic.
