Acan corals are a type of coral that grows in colonies. They are one of the easiest corals to maintain, and they can be found in both saltwater and freshwater aquariums. Acan corals are a type of soft coral that grows in a variety of colors and shapes. They are found at depths of up to 100 meters and are often red, purple, or brown, with white polyps covering their surface.

Coral polyps produce calcium carbonate skeletons that form a hard layer around the base of each polyp. This hard layer is called a skeleton or reef. This process occurs continuously throughout the year; however, it peaks during periods when sunlight is strongest and water temperatures are warmest. Coral polyps can grow very large; some species have been known to reach sizes greater than two feet across.

Acan corals grow best in an aquarium with proper lighting and water movement. If you have an acan coral that is not growing well or is dying, there are many things you can do to help it thrive again. Acan corals prefer to live in shallow waters with lots of sunlight and lots of space for them to spread out into their natural shape. They require ample amounts of nutrients, so they should be kept with other types of corals that provide food for them.

How Do Acan Corals Grow

Before you purchase an Acan coral, make sure you understand the basic principles of this reef-building coral. These include its anatomy, colors, and habitat. Having a clear understanding of these concepts will make choosing an Acan coral a simple process. If you have questions, don’t hesitate to ask.


Acan corals are among the most colorful corals in the world. Their tentacles are used for feeding and funneling food particles into the stomach cavity. The main source of energy for these animals is photosynthesis, which they achieve in conjunction with algae species called zooxanthellae.

While acan corals are largely photosynthetic, they also feed on detritus and other marine life that is floating in the water column. This provides some nutrition, but not enough to sustain the coral. As a result, these creatures are carnivorous.

Acan corals are found in tropical waters, particularly in the south Pacific. They are most common in the waters around Hong Kong and the Philippines. In their native habitats, they live in shallow waters up to 30 meters deep. Therefore, you should be prepared to use a waterproof watch that is capable of diving to such depths.

Acan corals are classified into different families. For example, the genus Acanthastrea includes eight species. The genus was reclassified after the Lordhowensis species was discovered to be closer related to the Micromussa genus. However, hobbyists had gotten accustomed to the name Acanthastrea for the rest of the species.

Acan corals grow best in tanks with proper calcium and magnesium levels. They need 350-450ppm calcium to maintain their skeletons. Magnesium is also important for maintaining its pH and coral growth. They require regular feeding and frequent water changes. You can also try to propagate them by fragging, but you should be careful and have enough experience.

Acan corals are semi-aggressive. They attack neighboring corals in their vicinity, so make sure that you give them enough space. However, they can be relatively compatible with other species, so don’t be afraid to add them to your aquarium.


Acan corals are one of the most popular coral reef aquarium plants. They require low to moderate lighting conditions and moderate water flow. These corals require no special care but they do need a meaty diet. Below are a few tips for keeping an Acan coral. Once you’ve established your tank’s parameters, you can add more colorful corals to your tank.

Acan corals come in a variety of colors, although the most common are red, green, and orange. These corals are between Micromussa lordhowensis and Acanthastrea bowerbanki in terms of size. They are also among the most colorful species.

Colors of Acan corals are marketed according to their appearance. Some types of acan corals are called “rainbow acan” or “ultra acan corals.” These corals can also be sold as “non-demanding” if you feed them regularly. These corals can be tricky to keep because they grow slowly and are hard to frag. Because their skeleton is intertwined throughout the colony, fragging can be difficult.

When buying acan coral, make sure to read the care instructions carefully and use proper techniques. Acan corals are slow growing, so make sure to frag them when new growth appears. This method is easy and fast, but it is important to give them time to heal. Although they do recover quickly from fragging, acan corals are susceptible to bacterial infections. You can treat the cut with iodine to prevent infection, or with a specialized coral dip to speed up the healing process. It is also recommended to use a bone cutter to cut the coral, instead of a conventional saw.

The food you feed your acan coral is essential. It will grow faster and healthier when fed regularly. It will extend its tentacles to seek food. Ideally, acan corals will eat meaty food in the water.


Acan corals are a type of stony coral. They have even walls and can be quite symmetrical in appearance. Each individual polyp has a skeletal cup known as a collarite, which can be up to 15mm in diameter. The septa located near the collarite’s wall are very thick, with long, fine teeth. It’s easy to identify acan corals by their shared walls, which appear like tiny folds when the polyps retract.

Acan corals require moderate lighting and moderate flow to grow. They can tolerate low light levels but will not do well with overly bright light. They can survive in most kinds of reef habitats, although moderate lighting will be best for them. If you plan to have an acan coral in your aquarium, make sure that there’s plenty of room in the tank.

Acan corals get most of their nutrition from zooxanthellae algae, which allow them to perform photosynthetic growth. However, they still require regular feeding to stay healthy. In order to keep your acan corals happy, provide them with small portions of food every two to three days. Feeding acan corals is easy and can be done with finely chopped seafood or thawed frozen food.

Acan corals thrive in shallower reefs and can reach depths of 98 feet. If you’re an aquarist, you’ll want to learn as much as you can about their natural habitat so that you can recreate the best possible environment for your corals. They’re easy to care for and are surprisingly hardy. Unlike many corals, Acan corals prefer a low-water environment with little movement. You’ll also want to make sure that your acan coral is kept away from other aggressive corals.

Lastly, be sure to monitor your acan corals carefully to spot any signs of stress. Some of the common symptoms of stress include skeletal exposure or bleaching. Once you determine what’s causing your acan coral’s stress, you can then make adjustments to its aquarium’s lighting or flow. However, make sure to change one variable at a time, as too much can unbalance the whole system.


There are many things to consider when choosing the best place for your Acan corals. This includes how they’re placed, the type of substrate, and how much space they have to grow. A good place for them is the bottom of your tank, on a sand bed, or on live rock. Each placement option has different advantages and disadvantages. For example, placing them on the bottom will give them a ball shape, but this will also limit their growth rate. On the other hand, placing them on a sand bed may have a negative effect, due to high water movement.

Acan corals do best in low to moderate light. In general, they prefer a sand bed and a moderate water flow. This allows food to pass between the colonies and keeps debris from building up. Place them on a rock island, however, and they will quickly take over.

Acan corals are aggressive and should not be kept in a tank with other corals. They are often engaged in coral warfare. Because they have no sweeper tentacles, they may be stung by corals with longer tentacles. As a result, they should be kept separate from other corals to avoid being stung.

Acan corals can be placed on the bottom or on rocks, but they are not recommended on the top or near the overflow of a pump. This is because they don’t like too much light, and placing them higher will result in them becoming bleached and losing color. However, they still need adequate lighting and moderate flow to thrive.

When introducing Acan corals to your reef, be sure to monitor the water’s pH and alkalinity. The ideal range for Nitrates is between one and ten ppm, and the ideal phosphate level is around 0.01ppm. If the phosphates exceed 0.10ppm, your Acan corals will start shriveling.


There are several factors to consider when feeding Acan Corals. First, the corals should be placed in a tank that doesn’t have too much water flow. Too much flow can cause the coral to close and cause problems with water parameters. In addition, it is not a good idea to have overly curious fish in the tank. These fish can be detrimental to the health of your corals, so you should move them to a different tank.

Acan corals are photosynthetic animals, which means that they get most of their nutrition from light. However, they also feed from the water column and consume zooplankton. So, while you might not think your Acan corals need feeding, it will be beneficial for them if you feed them occasionally. To ensure that they have enough food, you should feed your corals twice or three times a week. Initially, they may be reluctant to take food, so give them a little time to acclimatize.

When it comes to feeding Acan corals, the best way is to follow a consistent feeding schedule. This way, you will make sure your corals have enough nutrients to grow. You can also increase their health and make them happier. A good feeding schedule will increase the growth of your corals and give them a more vibrant color.

You can also use a syringe to make sure your coral receives its food. The syringe can be placed in the water and then placed over the coral polyps. The food will be sucked in by the coral’s tentacles, slowly digesting it and supplying it with essential nutrients.
