Captive breeding
A. Fish tank: 20 centimeters or more. It is a medium to large cichlid. It has a strong sense of turf, so it is advisable to keep it in a single tank. In addition, the size of the space will also affect the growth rate and body shape of the flower Luo Han. It is best to choose an aquarium that is over three feet in size so as not to limit the growth of the fish. Using black or blue as the background of the aquarium will help the flower luohan to show its best body color.
Substrate sand: Pearl rohu (including Taijin) prefers slightly alkaline water, and it is best to use coral sand for the substrate, so that the PH is between 7.2-7.6, and the thickness of the substrate sand is recommended to be more than 2 centimeters. The Golden Flower type Lohan (excluding those with obvious pearl bloodline) prefers weakly acidic water, and it is best to use volcanic rock or chicken blood stone as the substrate sand, so that the PH is between 6.5-7.0. Note: In acidic or weakly acidic water conditions, pearl type luohan is prone to blackening of the fish body and difficult to recover, or make the fish prone to gray sand.
Three, water quality: no matter raising any kind of fish, good water quality is quite an important part. The flower Luo Han is not strict on the water quality requirements, but because of its large amount of food, feeding should choose a good effect of the filter, so that not only can keep the water clean, increase the dissolved oxygen in the water and help to maintain the water stability of the water in the growth of probiotics. And it is best to change one-fourth of the new water every three days to reduce the nitrate content in the tank and avoid the occurrence of head holes, swollen mouths and protruding eyes. The water temperature of the adult fish is 26 ~ 28 degrees, the sub-becoming 28-30 degrees, and the fry 32-34 degrees, which is better.
Four, feed: you can use raw feed, small shrimp, red worms, no artificial coloring of the feed fed.
Fifth, lighting: most of the tropical fish in artificial farms, mostly stocked in small ponds outdoors, due to long-term exposure to daylight, so the color is very bright. When aquatic players bring tropical fish home to raise, if they do not mention **** fish only appropriate lighting, the color of the body surface will gradually fade. It is recommended to control the lighting for about 10 hours per day, which is good for the health and color performance of the fish.
Growing up to about 30 centimeters in length, the luohan fish is divided into pearl and golden flower strains, with many varieties under each strain.
