Lateral Line: The lateral line is a line of perforated scales along the flanks of a fish which lead to a pressure-sensitive nervous system.
Lateral line
The lateral line consists of a series of scales, each modified by a pore, which connects with a system of canals containing sensory cells and nerve fibers. It runs in a semi line from the gills to the tail fin.
Lateral Line
The sixth sense of a fish. The lateral line consists of a series of scales, each modified by a pore, which connects with a system of canals containing sensory cells and nerve fibers.
Lateral line
a visible line along the size of a fish consisting of a series of pore-like sensory organs acting as vibration receptors, or like sonar.

Lateral Line: A line of perforated scales along the side of a fish that is connected to a specialized organ used to sense vibrations in the water.
The lateral line
Running symmetrically along each side of the fish's body, the lateral line is more or less visible, according to the species. It consists of a succession of pores that communicate with a canal situated under the skin.

Lateral line Line of perforated scales along the flanks which lead to a pressure-sensitive nervous system. Enables fish to detect vibrations in surrounding water caused by other fishes, or reflected vibrations of their own movement from obstacles.
Lateral line disease
This problem condition affects certain species of marine fish, and those almost entirely members of the family Acanthuridae, Surgeon fish or Tangs.
· Lateral line or Linea lateralis = one or two lines of sensory organs along both sides of the body of most fishes, starting from the anterior of the gill cover to the caudal peduncle (see relevant entry).
The lateral line organ is a series of fluid-filled ducts located just under the scales. The lateral line system picks vibrations in the water. Thus fish are able to detect predators, find food, and navigate more efficiently.
The lateral line system is a sensor apparatus that reacts to vibrations in the water (sound). This helps a fish detect potential prey (food), predators or submerged objects.
Hole-In-The-Head or Lateral Line Erosion
Please note that the following remedies are anedoctal.
The information is presented as 'guidelines' to help you.

Name : Description : Small (1/4"dia max.) worms covered with 2 lateral lines of protruding white bristles. They grow to be at least a few inches in length. The body itself is segmented in brown and red.
The lateral line is incomplete or it is absent completely. They are very resistant fish but only the youngsters are friendly. In general, the can hardly endure the presence of other species in the same aquarium.
HITH- Hole in the head (lateral line erosion)- Oscars are very prone to HITH. Signs of HITH are usually very easy to see as the fish has lesions on it's lateral lines, or just above the gill plates.
They have no lateral line but most have lateral line organs chiefly on the head.
Though the body shape and finage varies by species, the dorsal fin is set towards the back half of the body.
The base color will be faint yellow with a darker brown, or black lateral line from nose to the end of the dorsal fin. The fins will usually be darker yellow with black markings.
macrops can be identified by its large eyes, oversize adipose fin, its fine pattern of dotting, and the dotted lateral line. Catfish from the river systems and basins of Africa are infrequently imported and not always available to the hobbyists.
Herbivore- Feed a diet rich in vegetable matter including frozen herbivore foods, dried seaweed, or live macro algae to help the Purple Tang retain its color and prevent lateral line erosion. Freeze dried algae sheets should be offered daily.
However, most fishes have sensitive receptors that form the lateral line system. The lateral line system allows for many fish to detect gentle currents and vibrations, as well as to sense the motion of other nearby fish and prey.
Head and Lateral Line Erosion (hole-in-head disease)
This disease can affect discus, other cichlids, and many saltwater fish. The fish develops holes in it's head and sometimes along its lateral line.
species by its red dorsal fin with a black blotch at the tip, red pectoral, pelvic and anal fins, red caudal fin with white margin and a black submarginal stripe along each lobe, and 8 scale rows between the dorsal-fin origin and the lateral line. B.
steindachneri the patch will include the lateral line of the fish, while in the similar species the patch lies above the lateral line. The appearance of the black patch in males is dependent on the individual fish and their mood.
It often migrates from the head to the lateral line and will sometimes follow the lateral line down the body of the fish. Needless to say, this is distressing to both the fish and the owner.
Now we know what it is, but how does it happen?
In addition, they possess the following characters: lateral line canal and pores chiefly on head, lateral line represented on body only by pitted scales; narial opening paired; branchiostegal rays 3-7; pelvic fins and girdle present or absent; ...
Distinguished from congeners in having a combination of the following characters: lack of elongate, symphyseal teeth on the dentary, a reduced lateral line extending posteriorly onto at least the caudal peduncle, presence of teeth on vomer, ...
The male has two black stripes running parallel to the lateral line, one running from the mouth through
the eye to the beginning of the caudal fin and the other lower on the body running from the throat to the back of
the anal fin.
Aside from this sensory lateral line, most fish have an inner ear, called an otiolith, which functions very much like the human eardrum.
Due to their generally poor eyesight, they rely on their lateral line, which is extremely sensitive, to detect changes in their surroundings and to hunt for their prey.
Signs of nutritional deficiencies in fish range from physical deformities, a lowered resistance to disease, lateral line erosion, loss of scales, and listlessness to physical blindness.
The Sohal Surgeonfish is hardy, but susceptible to a disease known as Lateral Line erosion, or Hole in the Head. A vegetarian diet high in vitamins, especially beta-carotene can aid in the prevention of development of the disease.
Not to be confused with the Flying Fox or False Siamese Algae Eater - A true Siamese Algae Eater has clear see through fins and the black lateral line runs right to the end of the tail.
The head, eyes, and scaled are large, and the lateral line is divided in the middle. The anterior rays of the dorsal and anal fins are spiny. Older fish develop a spinal hump and rough scaleds; they do not close their mouth in respiration.
The Gold Barb has a mostly gold-colored body with small, dark or black patches running down the lateral line. As the Gold Barb matures, the fin coloration develops into a striking red/orange.
Some will show some narrow reddish-orange lines below the lateral line, anteriorly on the fish. The upper half of the body is usually much darker. The most distinctive difference is the anal fins of the males.
Optically O. vittatus is easy to classify for the aquarist. The rhombic point on the peduncle at the the continuous lateral line makes it nearly unmistakable. Otocinclus species should always be kept as shoal.

Description: See pictures, Macropodus erythropterus has a more pointy head, a reddish region in the back, and if fully colored an irridescent bluecolor below the lateral line.
They infect the digestive tract and are associated with head and lateral line erosion. Symptoms: Fish will exhibit a marked decrease in vitality, darkened colors, lack of appetite, and slimy whitish-to-clear faeces.
The Cherry Barb is a more slender fish when compared to the other Barbs. The main body is silver/black with a golden, horizontal stripe following the lateral line. During spawning, the male will turn bright cherry red, which explains the given name.
Not feeding properly: Not feeding fish that need specific elements in their diet the particular elements that they need, not giving good variety, and feeding only flake food to most saltwater fish may lead to lateral line erosion, constipation, ...
sides of the head allow the fish to readily see what is next to them and move accordingly. However, sight is not the only factor used in schooling. Fish are able to establish their placement and direction in a school by using hearing, lateral line, ...
Some species are highly susceptible to head and lateral line erosion (HLLE) without proper diet and proper organic export equipment/protocol. Large Pomocanthid Angels like P.
All Asian arowanas are distinguished from Australian congenerics S. jardinii and S. leichardti by having fewer (21-26) lateral line scales (versus 32-36), longer pectoral and pelvic fins, and a longer anterior snout.
