Water for breeding of kissing fish
(1) activated carbon filter water: put activated carbon into plastic or enamel buckets and let tap water flow in from the inlet at the bottom and out from the outlet at the top. The filtered water is stored in aquariums or other containers, which can be used not only for daily breeding, but also for the breeding of ordinary tropical fish.
(2) filtering water with ion exchange resin: using ion exchange resin as filtration material, calcium ion, magnesium ion and nitrite in water can be adsorbed with the help of the adsorption capacity of anion and cation exchange resin, and the filtered water quality is neutral soft water. it is suitable for fish breeding of Cyprinidae, Cyprinidae and Cyprinidae.
(3) deionized water: also called distilled water. It is generally obtained by electrodialysis and electrolysis, and the water quality is very pure. The quality of deionized water is very soft, and the oxygen content in the water is very low, so it is not suitable to be used as breeding water. When in use, the method of mixing with clean water is often used to obtain water quality with different hardness and pH, so as to meet the needs of different varieties of breeding water.
(4) Rain Water: the water quality is soft and the content of metal ions is very small, so it is suitable to be used as breeding water for Cyprinidae and Cyprinidae. Generally, you can choose places with fresh air in the suburbs, use containers to hold rain and fall into the water, and then filter them for use.

Boiled red grouper
Raw materials: red spot fish, pepper, pepper (cut into small sections of about 2cm), sugar, salt, cooking wine production method: 1 wash the fish clean, take out the fish bone, start from the tail, the fish fillet is large and thin is the best. Add the right amount of salt, pepper, sugar and a small amount of cooking wine to the fish fillet and marinate for 20-30 minutes. Put the oil in the pot, wait for the oil to be 90% hot, first put the pickled fish head, deep-fried and put into the basin, then put the right amount of fish in the pan until all the fish are slippery. four

Prolapse of turtle penis
[cause] the testosterone in the tortoise is too high. [symptoms] normal turtles, sexually mature males, when mating during the breeding season, the penis is exposed to mate with the female, and after mating, the penis shrinks into the cloaca. The penises of some male turtles are occasionally exposed and immediately retracted. Abnormal male turtles, after the penis is exposed, can not be retracted in time, exposed for a long time, bitten by other turtles or scratched by foreign bodies, but also due to exposure for too long tissue necrosis, causing infection, and other diseases
