What is ocellate river stingray?
The cartilaginous fish of the order Rays, closely related to sharks, belong to the class of cartilaginous fishes, also known as the class of sharks. The order of rays includes 300 to 350 species. Also known as devil fish, it is a kind of shark that appeared in the Jurassic period of the Mesozoic Era (about 180 million to 140 million years ago). They have the habit of hiding in the sandy seabed. The body is flat, slightly round or diamond-shaped, cartilage without scales, pectoral fins developed, such as butterfly wings, the tail is whip-shaped, with venomous spines. Live under the sea. There are many species, the common ones are sharp-billed stingray, red stingray, swallow stingray and so on.
What does ocellate river stingray look like?
The difference between ocellate river stingray and sharks is that the body is flat, disc-shaped, with 5 pairs of gill openings and mouth usually located on the underside of the body; the difference from sharks is that the pectoral fins are huge and wing-shaped, born on the side of the body and head, above the gill openings . Many rays swim and breathe differently than sharks, using their pectoral fins as a motor for propelling their bodies; they use blowholes on the back of their heads to suck in water rather than through their mouths. The tail of the ocellate river stingray is generally slender, and many species have one or more sharp, serrated stingers that can be painful to sting.
ocellate river stingray is mainly marine. Many species live on the bottom of the sea and swim slowly. Manta rays (manta rays) feed on plankton and small animals; others feed on a variety of small fish and invertebrates, sometimes destroying commercially important shellfish farms. With the exception of rays, most or all rays produce juveniles. In vivo fertilization, the edge of the male pelvic fin is specialized as a mating organ, the splicer, which is used to inject semen into the female.
ocellate river stingray living habits
The living space of the ocellate river stingray should be wider. Take the common pearl stingray as an example, it needs at least a 5-foot fish tank.
Feeding is appropriate. The water quality of the ocellate river stingray, especially NO₂, needs special attention. Generally, the problem occurs about two to three days after raising the ocellate river stingray, and you need to be diligent in testing every day. The pH value is about six to seven, and the water temperature is about 24 When the temperature reaches 29 degrees, the water quality should be kept clear, and the filter equipment should be filtered at the upper part. The bottom sand should be fine sand.
The food is mainly loach, shrimp, and Zhu Wenjin, while the larvae are mainly mealworms, red worms, and small shrimps. It is especially important to note that before feeding shrimp, the shrimp arrows need to be pulled out to prevent piercing the stomach wall and causing misfortune. Buying ocellate river stingray is especially not greedy, because most of the ocellate river stingray is imported, so it is easy to die due to physical exhaustion or poisoning on the journey. Therefore, it is recommended to look at the fish first, and then buy it after 10-15 days. So much safer. Do not buy if you have trauma. The ocellate river stingray is a kind of ancient fish, and its regeneration ability is very good. Therefore, if the general trauma is not infected, it can be healed quickly. No need to add any medicine, just keep the water quality normal.
ocellate river stingray feeding
1. Feeding environment of ocellate river stingray
To know how to raise ocellate river stingray, you should first understand its living water quality. The suitable pH value of ocellate river stingray is around 6.5-6.8, which is a neutral weak acid. The second is the temperature. The temperature of the water in the tank where the stingrays are raised should be maintained at 26-28°C, but it should not be too high, because the excessively high water temperature will cause the residual food and excrement in the tank to rot and deteriorate, and the deterioration of the water quality will cause great harm to the health of the ocellate river stingray. influences. Therefore, it is necessary to regularly remove residual bait and replace the tank water, and at the same time, do regular water quality testing.
2. Ocellate river stingray feeding
Feeding is critical. ocellate river stingray is a bottom-dwelling fish and is a completely carnivorous animal. The bait selection is preferably sinking. Small fish and small shrimp can be used as bait. Generally, large fish eat Zhu Wenjin, creek shrimp, loach and minced fish. available for feeding.
It is worth noting that when feeding brook shrimp, the spines on the head should be removed. In addition, if the loach is large, it is best to cut it into small pieces. Stingrays do not have the concept of fullness. During the feeding process, it is best to control the feeding amount while observing.
