Corals

This coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues. It can also absorb dissolved nutrients from the water and may be offered zooplankton coral preparations, rotifers, mysis shrimp, enriched brine shrimp, oyster eggs, etc.Although Euphyllia corals can be quite hardy and not prone to pests, they are not tolerant of poor water quality and may fail to extend their polyps. Physical damage to the coral should be avoided at all cost, as it is prone to infectious brown jelly infection.This coral should be provided with plenty of space as it may produce long, powerful sweeper tentacles; low water flow helps to minimize the growth of these tentacles.With tentacles waving in the current in an almost hypnotic fashion, Hammer coral has charmed nearly every reef keeper at some point. Each tentacle ends in a single "T' shaped tip in a contrasting hue from its stalk.Many color combinations are possible, with Australian corals being more rare and impressive than those from other locations.Water flow is best provided as turbulent flow with the use of a wave maker or surge action. Constant laminar flow is very damaging and could cause death of the coral. Alkalinity, calcium, magnesium and strontium are required for growth and should be checked regularly.Difficulty:IntermediateGrowth Speed:Medium - FastLighting:MediumAverage Placement:Middle - HighWater Flow:Low - MediumTemperament:Aggressive

This coral receives some of its energy by utilizing the photosynthetic algae contained within its tissues. It also requires dissolved nutrients in the water and frequent feedings of phytoplankton and fine zooplankton, coral snow, and coral preparations such as Two Little Fishies Goniopower. Newly acquired specimens should be acclimated to intense light levels slowly to avoid bleaching. Few pests will bother it aside from syllid worms and flat worms. It is recommended to secure the coral so it does not fall off the rockwork, which may lead to brown jelly infections. This is one of the most difficult corals to keep and is recommended only to expert aquarists.Flowerpot may be either Goniopora, which has 24 tentacles, or Alveopora, which has 12 tentacles. Both Goniopora and Alveopora may have very long polyps while their relative, Porites, has very short polyps. They are sometimes called lemon coral because of their appearance when the polyps are retracted.Because of its requirement for frequent feeding it makes an excellent tank-mate with carnation, sun coral, filter-feeding gorgonians, chili sponge, as well as invertebrates such as sponges, tunicates, porcelain crabs, feather duster worms including those living within Porites coral, clams and oysters, cucumbers and sea apples, etc.Space should be provided between corals to allow for growth and expansion, as its polyps may be up to 12” long and have a strong sting.Without a doubt Flowerpot is one of the most alluring corals available. Its polyps dance and sway in the water, making for an incredible addition to the right aquarium. The purple variety may be deep violet to delicate lavender in hue. Ultra Australian colors are always exceedingly bright and impressive, and usually fluorescence brightly under actinic lighting.Water flow is best provided as turbulent flow with the use of a wave maker or surge action.

The Dendro coral is completely non-photosynthetic and receives all of its energy by capturing zooplankton. It will accept items such as mysis shrimp, enriched brine shrimp, oyster eggs, pellets, etc. Feedings should be as regular as possible, preferably every 24 hours. Unlike similar species such as Sun coral, Dendro’s polyps are usually open during the day time, making both feeding and enjoying this coral much easier. It does not require any light, and may be placed in a cave or under an overhang. It may also be placed near the surface (away from intense light) to make target feeding easier.Weak specimens may conserve energy by refusing to open; in this situation food may have to settle on the polyps for some time before it will eat. Unlike many other corals, each of Dendro coral’s polyps are separate and cannot share food with one another. Each polyp must be fed in order to thrive. Its polyps tend to be larger and more impressive than the more common Sun coral.Pests on Dendro coral are rare, but may include wentletrap snails or nudibranch. If regular feedings are provided it will reward the dedicated aquarist with the growth of new polyps. It is peaceful and should be protected from contacting other corals and their sweeper tentacles.Because of its requirement for frequent feeding it makes an excellent tank-mate with carnation, flowerpot, sun coral, filter-feeding gorgonians, chili sponge, as well as invertebrates such as sponges, tunicates, porcelain crabs, feather duster worms including those living within Porites coral, clams and oysters, cucumbers and sea apples, etc.Difficulty:IntermediateGrowth Speed:MediumLighting:Low - MediumAverage Placement:MiddleWater Flow:MediumTemperament:Peaceful

The polyps may expand so much as to totally hide the underlying skeleton, but will fail to do so under intense lighting, thriving better under more subdued light.Water flow is best provided as turbulent flow with the use of a wave maker or surge action. Constant laminar flow is very damaging and could cause death of the coral. Alkalinity, calcium, magnesium and strontium are required for growth and should be checked regularly.Difficulty:IntermediateGrowth Speed:SlowLighting:MediumAverage Placement:MiddleWater Flow:Low - MediumTemperament:Peaceful

Birdsnest coral is a type of pocilloporid, related to Stylophora and Pocillopora. They are some of the easiest small polyped stony corals to keep. Although they can be highly adaptable, they should still be provided with bright lighting and strong turbulent water flow best provided with a wave maker or surge action. It may be host to several species of beneficial crustaceans including Trapezia sp. crabs. In nature their polyps are open mainly at night, although in the aquarium they typically also open in the daytime. This coral may grow short sweeper tentacles less than 1”.This distinctive coral has extremely thin branches with tapered tips which may be quite sharp. As the colony grows they may become intertwined into a tangled bush. Color may vary, with ultra Australian specimens displaying brighter colors than those from other countries.This coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues. It will also benefit from occasional feedings of fine zooplankton and coral snow.Temperature swings are not tolerated and may lead to bleaching. Temperatures should never be allowed to reach 82F, which will surely damage the colony. For this reason many aquarists keep their temperature lower as a precaution, as low as 76F.Intermixing with soft corals (especially leathers, mushrooms and Lemnalia) is best avoided, as many soft corals release potent chemicals into the water which can be detrimental to the health of small polyp stony corals.Water flow should be strong and is best provided as turbulent flow with the use of a wave maker or surge action. Alkalinity, calcium, magnesium and strontium are required for growth and should be checked regularly.Difficulty:IntermediateGrowth Speed:Medium - FastLighting:Medium - HighAverage Placement:Middle - HighWater Flow:Medium - HighTemperament:Semi-Aggressive

Considered by many to be the pinnacle of reef-keeping success, Acropora corals are extremely demanding, but just as rewarding if given proper care. They require exceptionally stable water quality which can only be provided in a well-established aquarium over 6 months old. High levels of nitrate and phosphate are not tolerated and commonly cause browning; although low, stable levels are necessary for best growth and color. Alkalinity, calcium, magnesium and strontium are required for growth and should be checked regularly. Any instability leads to extreme stress which may lead to bleaching or tissue necrosis.They are very prone to pests, such as the red bug copepod, gorilla crabs, vermetid and Drupella sp. snails, some Asterina sp. starfish, nudibranches, flat worms, and boring sponges. All colonies should be dipped prior to adding to a display aquarium. Quarantine and removal of any substrate are also beneficial practices. It may be host to several species of beneficial crustaceans including Tetralia and Trapezia sp. crabs.Shallow water species have densely clustered polyps and need the brightest light, while those naturally from deeper water have sparse polyps with smooth skin and tolerate lower light levels. Newly acquired specimens should be acclimated to intense light levels slowly to avoid bleaching. Species with thicker branches demand the highest water flow. Acropora are related to Montipora but tend to be much more difficult to keep.Space should be provided between corals to allow for growth and expansion nematocyst laden acontia filaments, which are digestive organs that can kill neighboring corals.With a huge diversity of dazzling colors and shapes, it’s no wonder Acropora are some of the most popular corals of all. Ultra Australian specimens are always breathtaking colors and are very often multicolored. These are some of our very best corals available and will not disappoint. Many species will display white or contrasting colored growth tips. They may even resemble many of the name-brand varieties available online that sell for much more.This coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues.
