    Anemone is a class of six subfamilies of corals. Although anemones look like flowers, they are actually predators and the most common invertebrates. This invertebrate has no bones and anchors on fixed objects on the seabed, such as rocks and corals. They can move very slowly.

    As one of the huge invertebrates in the ocean, sea anemones often coexist with the clownfish. This is one of the characteristics that people usually recognize. There are many types of sea anemones. Here are a few of them.

    1. Hawaiian Anemones

    Hawaiian Anemones look like flowers, but they are actually predators. They have a colorful body, brown-green inside, and bright tones on the outside. Hawaiian anemones like to live alone and sometimes live with sea shrimp. Their food is shrimp, shellfish, fish meat and frozen feed, suitable for growing in an environment with a water temperature of 23-27 degrees, a seawater specific gravity of 1.022, and a light of 10,000-20,000 lumens.

    The cylindrical body of the Hawaiian anemone is firmly sucked on the rocks, silt on the bottom of the sea by a strong suction cup at the bottom, and even adsorbed on the shells of shellfish and crabs. They are big and small, small ones are like rice grains, only 0.05 cm high and 0.2 cm in diameter, slightly larger ones are like fingers, and the bigger ones are like bowl mouths, the larger ones are up to 30 cm in diameter, and the diameter of the mouth plate is more than 60 cm. The upper end of the body of the Hawaiian anemone is its disc-shaped mouth, and the mouth is covered with soft tentacles, which have various exotic colors. Some kinds of tentacles have only one circle, and some kinds of tentacles are arranged in several circles, increasing by a multiple of six from the inner layer to the outside, and more than 200 tentacles. The bright colors of sea anemones are due to the symbiosis of single-celled algae in the sea anemones. The carbohydrates it produces can be used by anemones. In addition to catching small fish and shrimp, unicellular algae are also one of the basic foods of anemones.

    2. Stichodactyla Haddoni

    The Stichodactyla Haddoni mouth is thin and spherical, covered with short tentacles (projected. But sparse, only one or two per pinch), arranged in five pinches on the edge. There are obvious cnidaria tissue on the tentacles. It seems to stick to the body, but it is easy to pull it off. Stichodactyla haddoni are used to living alone, growing alone on coral reefs or soft seabeds, with many symbiotes and shrimps symbiotic. They are more difficult to raise and require strong light and moderate water flow. Feeding Stichodactyla haddoni requires a salinity of 1.020-1.025 and a pH of 8.1-8.4. It is best to keep Stichodactyla haddoni at a water temperature of 23-27°C, a seawater specific gravity of 1.022, and a light exposure of 30,000-50,000.

    Stichodactyla haddoni come in many colors, and the body is transparent or shiny in white, yellow, green and purple. It was covered with flesh bumps. The mouth is sometimes directly on the ground, sometimes slightly off the ground, and the mouth plate is 75 cm long without the tentacle. Nutrition can be supplemented by parasitic algae that live on it. Its cytic cytotoxicity is very strong, but people’s skin will not hurt when touched. They have a fierce temperament. If they are attacked or threatened, it will eject a milky liquid depending on the distance of the enemy, making the water instantly white and turbid, so it can take this opportunity to make the attacker blind, his feet It can be 40 cm deep into the ground.

    3. Stichodactyla Mertensii

    Stichodactyla Mertensii are huge in size, covered with tentacles, blunt and finger-like in shape, and all of them are brown in color. Sometimes they will change color due to the influence of symbiotic algae, but most are dark. Stichodactyla Mertensii require strong light and good water flow. They should be provided with sand bottoms or rock structures for them to inhabit. They like to bury their feet in the sand and sometimes attach themselves to the wall of the tank. When it likes one or more habitats, it will search in the tank itself until it finds a suitable location. When the condition is good, the tentacles will be very sticky. If it grasps anything (or hands), it is difficult to take it out without harming it, so be careful when holding it by hand to prevent stinging.

    Stichodactyla Mertensii are also difficult to maintain. Mature sea tanks, stable water quality, moderate water flow and stronger light will help them grow. After adjusting to the environment, it is best to feed some food every week, including fresh fish, fresh shrimp and other Animal food. Of course, the symbiotic algae present in the body of the Stichodactyla Mertensii can also provide most of the required nutrients through photosynthesis.
