Elephant trunk fish is a more popular ornamental fish, but because the fish is more ferocious, it is best to keep it alone. Is the elephant trunk fish good for raising? What details should be paid attention to during the rearing process? The following Xiaobian will briefly introduce the habits of the elephant trunk fish.
The weevil is a genus of weevils in the family Sturgeonidae. It is named for its lighter body color. Also known as lyrefish, swordfish, ancient name tuna. Body length fusiform. Both the upper and lower jaws have sharp teeth. The snout is longsword-shaped, and its length is 1 for the length of the head behind the eye. 5～1。 8 times, the snout gradually widens from front to back, the front end is blunt and pointed, narrow and flattened, and the base is hypertrophied. The body is boneless and large hard scales; There is only a row of spiny scales on the upper margin of the caudal fin , with a pale purple-grey back and a slightly white-pink tinge on the abdomen and each fin. It has important academic value in the origin, evolution and geographical distribution of fish.
In terms of body structure, the weevil has a fusiform body, with a slightly flattened anterior part, a thick middle section, and a slightly lateral flattened posterior part. The head is extremely long, more than half the length of the body, and it is covered with plum-like traps. The ventral surface of the head of the snout can be freely retracted. In ancient books, there is a record that "the mouth of the tuna is under the jaw, and the long-nosed cartilage is also", and the ecological characteristics of the weevil fish are concisely summarized. The upper and lower jaws have small, pointed teeth; The snouts are a pair, short, located on the ventral surface. The eyes are small, with a pair of tiny whiskers, located on the ventral surface of the kiss. The orifice is large, curved, telescopic, and located on the ventral surface of the head. There are 2 external nostrils on each side of the head. The entire surface of the head membrane is densely covered with many fine plum-shaped sensory nerve cell tissues. The lateral line of the body is intact, the tail is crooked, the upper lobe is long, the lower lobe is short, the upper lobe has spiny scales on the back, and the body surface is smooth and scaleless. The upper lobe of the caudal fin has 8 prismatic scale plates that extend backwards to the upper lobe of the caudal fin. The dorsal fin starts after the ventral fin and consists of unbranched fins. The caudal fin is crooked, the upper lobe is well developed, and the leading edge has a row of spiny scales. The intestinal tract is short, with 7 to 8 spiral valves in the intestine. The head , dorsal and caudal fins are bluish grey , and the abdomen is white.
Elephant trunk fish feeding points:
Weevil fish are more sensitive to water quality, and people in the origin use this fish to monitor water quality. Elephant trunks are tropical fish and are also sensitive to temperature, requiring water temperatures around 24 to 29 °C! A hot and cold water temperature will cause a sudden change in water quality, causing uneasiness in the fish, some fish may crash into the tank, uneasiness, and the trunk may also discharge. However, then again, as long as the weevil fish is eaten, it is easy to raise, the larger the more fierce, but the mouth is small, slow to grow, the largest has seen 30cm + individuals, very beautiful!
