The Malacanthinae are a group bass related marine fish, which in contrast to the brick perch the (Latilinae) as a second subfamily Torpedo perch be assigned (Malacanthidae). They occur in the Indo-Pacific and in the western Atlantic . There are only two types. Torpedo perches of the Malacanthinae subfamily are occasionally imported for saltwater aquariums, but usually do not survive long because they are caught with poison.
features
They are slimmer and more elongated than the tile perch, their head profile is round. They lack the bone crest in front of the dorsal fin , which some species of tile perch have. The thorn on the gill cover is very large and pointed. The dorsal fin of the genus Hoplolatilus is supported by three to ten fin spines and 13 to 34 soft rays, in the genus Malacanthus there are one to ten fin spines and 43 to 60 soft rays. In both the anal fin has one to two fin spines and 12 to 55 soft rays.
Way of life
The Malacanthinae usually occur in shallower water than the tile perch, usually not below 50 meters. They live in pairs or in larger colonies in self-dug residential tubes or in large castles piled up from mussels and rubble close to the ground at depths of 20 to 100 meters. The piles of rubble can be several meters long. Most species feed on zooplankton , which they snap up in the open water - always staying close to the shelter.
Genera and species
There are two genera and 14 species:
