After we finished talking about clownfish, let's talk about a fish that is also common in sea tanks - hanging species.
Hanging fish, a genus of spinytails, lives in tropical oceans, especially near coral reefs, with most species distributed in the Indo-Pacific Ocean and a few in the Atlantic Ocean. Most eat benthic algae, and a few eat plankton.
The fish is olive-shaped, with small scales and fixed to the skin, making the skin as rough as sandpaper, generally 20-30 cm long and up to 70 cm.
The biggest feature of this fish is that it has a pair of spikes, located on both sides of the base of the tail, which is very sharp, and is known as "stickleback".
The general temperature is between 26-28 degrees, it is recommended to raise more than 300L of water, in the ocean hangers have to swim tens of kilometers every day to find food, so they can escape parasites, but in the sea tank, the hanging movement space is limited, and the mucous membrane on the body surface is not as thick as other fish, so it is very easy to get skin parasites such as white spot disease.
Plant-based food can also be fed animal food, but providing enough plant-based food such as seaweed and seaweed can enhance immunity, make colors more colorful, and reduce aggression. Natural algae flakes and green algae flakes can be provided first, and then gradually converted to pelleted feed.
Let's talk about common hanging classes
Blue hanging, the body is dark blue, the upper pectoral fin is black from the center to the tail, but there is an oval blue spot behind the pectoral fin. This fish grows to 14 cm of gonads and begins to develop and spawn, and gradually degenerates, and more than 17 cm is male. It feeds mainly on tiny zooplankton and algae.
Blue hanging's personality is mostly lively and docile, and sometimes bullied by other fish. The better the water quality, the deeper the blue hanger will be, and on the contrary, it will fade and dull.
Hanging in a single line, the juvenile is yellow throughout, with an inconspicuous orange-yellow transverse spot behind the eyes, and a pale blue dot can be seen between the and dorsal fins. As it grows, the body gradually turns grey-brown, the adult is grayish-white in front of the body, the rest is black-brown, and there is a dark blue-edged orange-yellow spot behind the eyes. Juveniles are similar to those of the yellow triangular hanging and chocolate hanging , but the fin of the other two species does not have pale blue spots.
Gentle temperament and friendly to other hangers.
Colorful hanging, most of the fish body is chocolate-colored, the face is white, the base of the dorsal fin and fin is bright yellow, each fin has a blue-white edge, there is a relatively wide white stripe from the eyes to the mouth, and there is an orange stripe at the back of the outer edge of the dorsal fin.
Tengu hanging, also known as Japanese upside down hanging, is named because the facial pattern resembles the image of a tengu in Japanese opera. According to the origin, it is divided into Pacific tengu crane and Indian tengu crane (mostly Pacific tengu crane). Juveniles are dark grey , with blue stripes on the dorsal fin and orange stripes on the tail fin , a reddish-brown body when mature, an increase in color on each fin , a small black mask appears between the eyes and mouth , and the mouth gradually becomes orange-red.
Golden retriever, juvenile fish have a gray-white body surface, and the body will turn blue-gray as it matures. There is a yellow band from the lower edge of the eye to the mouth, the outer edge of the nostrils is white, the upper and lower lips are orange-yellow, and the upper and lower fins are elongated to filamentous in males and not in females. The Golden Retriever turns completely black when fighting, hides gray-black with a gray half when frightened or sleeps, and is blue in natural waters, which is very interesting.
Rocket hanging, the juvenile body is gray, gradually turns dark green as it grows, becomes yellowish brown after adulthood, the breast is white and blue, there are no stripes on the side of the body, the eye circles are black-brown, and there is a white spot in front of the eyes. The dorsal and fins end in yellow, the ventral fin is green, and the pectoral fin is transparent. There is a black spot on the upper and lower sides of the caudal peduncle. The caudal fin is whitish and bluish.
Large sail hanging, the oval body with several distinct vertical stripes from yellow-brown to black, each striped in complex color. The dorsal and ventral fins look like sailing ships when open. The tail color transitions from white to brown.
