History

In 1996, Malaysian aquarium operators cultivated a brand-new species of fish-"Luohan" through continuous cross-breeding. , and triggered a boom in the cultivation of Luohan fish. It swept the entire Asia-Pacific region in an instant, and fish fans in Singapore, Japan, Taiwan and other places rushed to buy it, causing a great uproar in the aquarium industry. Luohan fish is collectively known as color sea bream in Chinese, which means colorful cichlids, also known as flower arhat.

What is so unique about the "Luohan" fish? If you look closely at a Luohan fish, you will unconsciously be captured by its humanized form. The rosy cheeks and the towering forehead symbolize longevity and longevity, and the "ink-spotted scales" with different shapes on both sides are even more magical in Feng Shui.

Luohan fish has a bright and colorful body color, which meets people's needs in visual experience. However, the color under the condition of captivity will be very different, and what is the source of this color determines the choice of feed under the condition of captivity. After research and analysis, the main color component of Luohan fish body surface is astaxanthin. Astaxanthin is combined with fish skin and fish scale protein, which presents colorful colors under the action of light. However, animals themselves cannot produce astaxanthin and must obtain it through the food chain. Under natural conditions, fish forage for algae, shrimps, crabs, shells and other foods, and obtain astaxanthin; in the artificial breeding environment, the demand is met by adding corresponding ingredients to the feed. At present, the ornamental fish feeds on the market mainly use chemically synthesized astaxanthin and algae-derived natural astaxanthin as the main ingredients.

Habits

In addition to the majestic and majestic king's momentum, the dazzling and moving colors, and the lovely humanized appearance, Luohan is the most popular among the fans. One of the hardest parts of indulging in them is the complex between them and their owners.

Luohan is very ferocious to other fish, but very spiritual to people. As long as the owner comes to the fish tank, the Arhat will swim up intimately and play with the owner. Or swim, or flip, or lie in the owner's hands, enjoying the owner's caress. As tame and cute as a dog. But if a stranger also wants to get close to Arhat like this and play with him, he will definitely attack him mercilessly, leaving a mouth print in the lightest, and blood in the heavy. With such a spirited Arhat, it is no wonder that many families treat him as a pet.

But because of its early start, the body ink spots and beautiful color, it is still the main force in the market.

Golden Flower Arhat is a species of Arhat with strong potential ornamental value. Its external appearance is a square umbrella tail with a long lifespan, but its maturity is relatively late, and its head is usually a cannonball head. After a year and a half, it shows a very high ornamental value. Generally, most of them are white eyes, and some are red eyes. Blue eyes have the highest ornamental value.
