Mini reef aquarium guide. Reef aquarium setup for large reef tanks, Nano reef tanks, Pico reef or MIcro reef aquariums with reef tank lighting, filtration, choosing coral reef animals, and problem solving!
This video has great pointers and care times for the Acan corals! Acans need to be fed quite often and with mysis and similarly sized foods. The video will show how to propagate and how to feed them. Soft corals can produce toxins that can inhibit and possibly kill your Acan, so use Poly Filter or Purigen to keep the chemical war to a minimum!
This is a short video that gives a quick glimpse of the breathtaking colors that the Acan Lord can be found in! Their skeletal walls vary in height and the polyp or corallite centers are often a different color than the surrounding flesh. They are hungry corals, happy to eat mysis and similarly sized foods every other day! Squeezing some "juice" from the food over the colony will get them to open up and extend their tentacles, at which time you can directly feed them minced meat! They do not do well in strong lighting and need low to moderate light and moderate water flow.

Yet another reason to go EUPHYLLIA!!!! Not only will all the different species of Euphyllia get along, even touching each other, they will host willing clownfish! This gives the beauty of a symbiotic relationship right in your tank with the durability of a coral that looks like an anemone during the day! Feed daily with pieces of minced raw marine flesh and keep large softy populations that are noxious out of the tank, and you will be fragging your Euphyllia in no time!
This is a great video of both Black and Yellow or Orange Sun Corals in the Gulf of Mexico. They have happily attached themselves to an oil rig along. In 1943, the Sun Coral, T. coccinea, was introduced into Atlantic waters and have competed successfully for space with native coral. The Black Sun Coral, T. micranthus, is a recently introduced invasive species, discovered in 2010. They are not native to Atlantic waters, but are originally found in the Indo-Pacific.
Black Sun Corals are unlike their sun loving cousins! They are not restricted to areas of sunlight because they are non-symbiotic corals call azooxanthellate species. They are great for building reefs in the wild as a base coral, but need a lot of food to survive! This lack of need for light makes it so that they can live in water that is thousands of feet deep, live in caves and live in colder waters as well. Using the stinging cells on their tentacles they trap live prey in the wild. Feeding them daily.
Hard corals are generally broken down into two categories; large polyp stony (LPS) corals and small polyp stony (SPS) corals. The LPS corals are generally larger calcareous corals. They have much larger fleshy polyps than those of the small polyp stony (SPS) corals.
Many LPS corals are quite hardy and can even be fast growing. These stony corals are generally easier to keep in the aquarium than the small polyp stony (SPS) corals. For the most part they require less intense lighting and a lower water movement than SPS corals.
Both of these types of corals lay down calcium on a hard skeleton via the polyps. Thus the name names stony coral or hard coral. This means they require adequate levels of calcium to thrive. Generally a level above 400 ppm is desirable. Many authors recommend 430-480 ppm calcium for these corals. Other elements needed for many of these corals to thrive are strontium, iodine, and trace elements. Many of these corals can be fed small bits of seafood (shellfish, crustaceans, squid, fish), but as they derive much of their nutrition from the zooxanthellae contained in their tissue, feeding is usually not necessary.
Corals like these will propagate either by spawning or by "budding". This means the parent will grow small corals that will separate from the parent, or the parent will simply separate into multiple corals.
Many of these corals have long stinging tentacles called 'sweeper tentacles' which serve to cut down on competing corals in the nearby vicinity so you must give them plenty of room in the aquarium. See the Frogspawn coral for a picture of sweeper tentacles.
The coral reef is a beautiful world; comprised of anemones, mushroom corals, corals, crustaceans, and a myriad of other incredible animals. The word coral itself brings to mind the reef building hard corals, or stony corals. Stony corals produce a skeleton of calcium carbonate, which then becomes the foundation and building blocks of the coral reefs.
The Large Polyp Stony (LPS) Corals are a large and diverse group. They can have complex elegant shapes, and fascinating colors. Convenient terminology in the aquarium industry is to describe stony corals as either SPS corals (small polyp stony corals) or LPS corals (large polyp stony corals). What they look like becomes immediately obvious when you compare the size of their polyps. LPS have much larger polyps than the SPS. Though this generally works pretty well in recognizing a particular type of coral, it isn't an exact description. There are occasional coral species whose polyps don't fit the norm of their group, being too large or too small.
Types of Coral
Some LPS favorites include the Elegance Coral, Hammer, Galaxy, and Torch Corals, Frogspawn, Fox or Jasmine Corals, Disk and Plate Corals, and Bubble and Pearl Corals.
The following are those corals usually referred to as Large Polyp Stony (LPS) Corals:
Keeping a bit of coral reef in the home aquarium is an exciting and rewarding adventure. Reef tanks were once considered very difficult to keep. Keeping live coral is still somewhat demanding, but today the knowledge and equipment are readily available to the average hobbyist.
Beautiful home reefs can be either a simple reef with hardier, less demanding animals, or a more complex reef with higher maintenance specimens. Stony corals are more demanding and take a more dedicated effort. So keeping stony corals is itself a step beyond a simple or beginner reef.
Having reef-keeping experience is invaluable to successfully keeping hard corals. With some of the less demanding inhabitants you can hone your skills. You will develop an understanding of the unique habitat these animals thrive in. Some of the best inhabitants for a beginning reef are soft and leather corals, coral anemones, and anemones. Once you've gained success in keeping these, you will be ready to keep the more delicate and demanding stony corals.
Anyone with the desire to learn specific husbandry techniques and the willingness to purchase the proper equipment can keep a gorgeous reef aquarium. Of course the aquarist must invest his or her time in the care of these unique animals as well. See the individual corals for details on keeping each species in the aquarium.

Large polyp stony (LPS) corals are some of the most difficult corals to propagate in captivity and many specimens are wild caught. However, experience over the last few decades has strongly indicated that captive bred stony corals are much more adaptable and hardy than wild caught specimens. So it is better to acquire captive bred large polyp stony (LPS) corals when possible. You'll not only get a more durable coral, but there are often many beautiful color morphs available.
