The family of the lyre fish (Callionymidae) is a group of the perch relatives (Percomorphaceae). There are 20 genera and over 190 species .

distribution

Almost all of them are bottom-dwelling fish of the tropical Indo-Pacific . In the Mediterranean seven species of live Callionymus . Lyrefish live on sandy bottoms and reefs.

Appearance

Lyrefishes are small, elongated, scaleless bottom fish. They have two dorsal fins , the first has one to four hard rays (it is completely absent in two species). There is a sexual dimorphism in many species ; Males usually have a larger and more colorful first dorsal fin. The pelvic fins are very large and widely spaced. Lionfish use their ventral fins as supports when resting on the bottom. The head is large, triangular when viewed from above, the mouth small and pointed. The eyes are up. The front gill cover has a strong thorn, which can be studded with barbs, the gill cover is thornless. The gill opening is only small and lies on the top of the head. The lateral line organ is complete. Lyrefish are two to 30 centimeters long, depending on the species. Many lyre fish are very colorful.

Fin formula : dorsal 0-IV / 5-11, anal 4-10

Aquarium keeping

Some species of lyrefish are popular ornamental fish and also show interesting courtship behavior in saltwater aquariums . The two most colorful species are the mandarin lyrefish ( Synchiropus splendidus ) and the LSD lyrefish ( Synchiropus picturatus ) found in the reef . Both species have already been bred in the aquarium. The more sand-bound and not so conspicuously colored star-headed lyrefish ( Synchiropus stellatus ) and eye-spot lyrefish ( Synchiropus ocellatus ) are also offered more often. Other lyrefish are very rarely seen in saltwater aquariums.

Lyrefish are not easy to keep because they have to eat constantly and a small aquarium often does not provide them with the necessary live food.
