Angelfish breeding and breeding

Morphological characteristics of angelfish Angelfish, aka fish, angels, angelfish, finfish, genus Rico, native to South America, Guyana, Brazil. The angelfish are 12-15 cm long and 15-20 cm tall. The heads are small and sharp and flat and are diamond-shaped. The dorsal fins and anal fins are very tall and grow up like a jib, so they are called finfish. Seen from the side of the angelfish swimming, as the swallows soar, so the angelfish was also Yan fish.
Angelfish pelvic fins have evolved into tentacles, soft white, long fringe. The tail shank is short, the trailing edge of the tail fin is straight, and the upper and lower ends are slightly longer. The pectoral fins are colorless and transparent. The surface of the pectoral fins is colored with silver and yellow, abdomen is silvery, and the back is light golden. Each side has four black rough lines. The first one passes through the eyelids and the second one is at the base of the dorsal and anal fins. Three from the dorsal fin end to the anal fin end, the fourth at the base of the caudal peduncle. The outer eye of the black eye of the eye is red with a black velvet strip.
The angelfish is quiet, moving and unrestrained. It suddenly rises and falls in the water. Suddenly it flies and floats. If it is a fairy, it is known as the "Queen of Ornamental Fishes" for its peculiar shape, graceful swimming and elegant colors. Feeding angelfish requires angelfish to be gentle in character, graceful in swimming, and difficult to raise. It requires that the terrarium be large and that it should be planted with broad-leaved plants that can have a few hours of light each day. Angelfish does not have strict requirements on water quality. Hi to live in weakly acidic soft water with a pH of 6.5-7.0, suitable for a temperature of 26-30 degrees Celsius.
Angelfish prefers fresh water that has been air-laid. Frequent water changes will reduce their chances of getting sick.
Angelfish do not choose to eat, but they like to eat large fresh live bait. Angelfish can be mixed with other species of tropical fish, but it cannot be in the same tank as tiger skin fish because tiger skin fish will bite the anal fins and caudal fins of angelfish.
The identification of male and female angelfish is difficult to distinguish from male and female reproduction of angelfish. In general, the head of the female fish is smooth, and the head of the male fish is slightly raised; the abdomen of the female fish is swollen and the male abdomen is normal; the female fins are shorter than the male fish.
Angelfish is an oviparous fish that matures at 10 months of age. Angelfish have "freedom of love" and find their own habits of mate. If they violate their wishes, they will "pull the langs", which will often lead to reproductive failure. Therefore, after the angelfish enter the breeding period, it is necessary to pay attention to observation. If it is found that two fish often swim together, eat, and the anus hangs prominently, it is necessary to fish it into a pre-prepared breeding tank. When the male and female fish are in estrus, a very thin vas deferens can be found on the lower abdomen of the male. The color is light white or yellow-white and is about 0.5-1 mm long. The abdomen of the female fish will enlarge, and at the same time, the lower abdomen will apply a 1 millimeter-long, thicker fallopian tube with the same color as the male.
Angelfish love to lay eggs on the leaves of broadleaf weeds, such as waterless grass, can use a piece of frosted glass (or stainless steel, glass tile, plastic plate) to place the bottom of the cylinder to make a 45-degree angle with the cylinder wall, as an attachment to the spawning cloth. At this point, both male and female will use the mouth to clear the frosted glass plate, commonly known as the "seesaw". Within 1-2 days, the female will lay eggs on the plate, and the males will then fertilize the eggs to fertilize the eggs. This is repeated many times and completed in hours. Each female can produce 400-1000 eggs per breeding.
At the end of spawning, male and female fish have the habit of co-protecting eggs. They take turns to use the pectoral fin to fan the water on the eggs to provide oxygen for the fertilized eggs. When they hatch, when they find unfertilized white eggs, the male and female fish will use their mouths to Clean up, do not mistakenly eat fish eggs.
The breeding water of angelfish is generally pH 6.5-7.4, hardness is 7-10, and the suitable temperature is 27 degrees Celsius.
Fertilized eggs hatch into larvae after 2 days. Newly hatched larvae do not swim. They continue to develop by absorbing yolk sac and remain on the attachment for 1 week. During this period, the broodstock has been protecting the larvae. If larvae are found falling into the bottom of the tank, the brooders will pick up the attachments from their mouths. Male and female brooders sometimes beat each other during care of the eggs and larvae. If this happens, male fish should be removed and the female fish must be cared for separately.
After larvae have hatched for 1 week, they will “underrun the plate and swim for food. The broodstock will lead the herds. The brooders must not be disturbed while nursing the larvae, otherwise they will swallow the fertilized eggs or larvae. After another 1 week, they can When the larvae start eating, they should feed “dumpling water”, and they can feed small fish and worms in 7 days, and after 1 month of age, they can feed the same bait with the adult fish.
The angelfish, a species of angelfish, was artificially reared to form many new varieties. There are: Jintou Angelfish, its body gray yellow, no obvious black rough lines, red and yellow forehead, covered with a transparent lid; 鸳鸯 angelfish, also known as black and white angelfish, the first half of the body like ordinary angelfish, the latter half Black angelfish; marbled angelfish, full of gray, mixed with irregular black-and-white marble patterns; black angelfish, its body is black, fins are underdeveloped; glass angelfish, its body is translucent, cover transparent, can be See red dragonfly; and red-eye goldfish, grey angelfish, zebra angelfish, white angelfish, etc.
If it is divided into the length of fins, it is also known as the long-tailed angelfish, the mid-tail angelfish, and the short-tailed angelfish.


Quartz Sleeve



We provide quartz sleeve for the uv lamp.


The quartz sleeves are probably the most abused components of a UV system, yet they are one of the most critical for delivering UV rays into the water stream.


Sleeves provide a protective barrier around the lamp so that the lamp can operate at its optimal temperature. For the quartz sleeve to maximize a unit`s performance, both the interior and exterior of the sleeve must be cleaned periodically, even in UV units installed in ultra-pure water systems. All quartz sleeves are susceptible to fouling.

Cleaning frequency of quartz sleeves will be site-specific and directly related to water quality. UV systems that are installed in post-reverse osmosis/deionization (RO/DI) locations will require cleaning much less frequently than units installed on raw water or surface water systems. As a general rule of thumb, a post-RO/DI system should have the quartz sleeves cleaned once a year.


Plan on cleaning quartz sleeves quarterly on post-activated carbon systems and more frequently for hard water applications exceeding 5 grains of hardness.


Standard clear quartz glass tube is high quality purity and automatic controlled fusing furnace

It has the characteristics of high purity,strong resistance,high transmission and accurate dimensions,and the OH content 1-20ppm after air of vacuum baking is available.
