Hydnophora Exesa
Hydnophora Exesa coral, also known as Horn Coral, Knob Coral, Velvet Horn Coral or Branch Coral, originates in the Indo-Pacific ocean, Figi, Tonga, Solomon Islands, the Great Barrier Reef and Eastern Africa. It is considered a Small Polyp Stony coral (SPS) and is considered highly aggressive towards other marine aquarium invertebrates. Hydnophora Exesa is not readily available and never found in abundance.
Hydnophora Exesa Morphology
Hydnophora Exesa coral is moderately hardy. The Hydnophora Exesa species is generally characterized by mound shaped structures called hydnophores from which the polyps emerge. The skeleton of this species is branched, flat and irregular in structure, and are generally green, brown or yellow (when it doesn't get enough lighting). This type of coral has sweeper tentacles for feeding purposes.
Habits And Habitat Of Hydnophora Exesa
Hydnophora Exesa should be placed anywhere between the middle and higher level in your stony coral dominated aquarium. Hydnophora must have plenty of room, at least five inches all around the coral, so that it can spread without any obstruction. Keep all other marine invertebrates away from the Hydnophora Exesa species in your marine aquarium. This type of coral is highly aggressive and pack a potent sting to unsuspecting neighboring coral and even humans.
Hydnophora Exesa Illumination And Water Flow
The Hydnophora Exesa species requires high lighting in the marine environment it inhabits. Water flow to the Hydnophora coral needs to be high and intermittent water current. Metal halide lighting or actinic lighting in blue shade are recommended. Fluorescent lighting and power compacts are also fine as long as they are high output. The coloration and growth of Hydnophora coral may vary depending on the intensity of the light.
Feeding Hydnophora Exesa Coral
The Hydnophora Exesa species derives its nutrition mainly through photosynthesis, which is performed by zooxanthellae, a photosynthetic algae living symbiotically within the coral. It can also be carnivorous in feeding habit and filter feeds a few times a week, when open. It is important to keep the calcium, strontium, and iodine levels up in the aquarium, and the phosphate and nitrate levels as low as possible for best Hydnophora health.
Care And Caution Of Hydnophora Exesa
Hydnophora coral is difficult to maintain, and is not recommended for beginner aquarium enthusiasts. This type of coral has powerful stings, and it should be kept as far away from other coral species as possible because Hydnophora Exesa may sting them, which may result in death of the coral.
