Green Hydnophora

Green Hydnophora 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. Green Hydnophora is not readily available and never found in abundance.

Green Hydnophora Morphology

Green Hydnophora coral is moderately hardy. The Green Hydnophora 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 a brilliant almost fluorescent green. This type of coral has sweeper tentacles for feeding purposes.

Habits And Habitat Of Green Hydnophora

Green Hydnophora 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 Green Hydnophora species in your marine aquarium. This type of coral is highly aggressive and pack a potent sting to unsuspecting neighboring coral and even humans.

Green Hydnophora Illumination And Water Flow

The Green Hydnophora 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 Green Hydnophora coral may vary depending on the intensity of the light.

Feeding Green Hydnophora Coral

The Green Hydnophora 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 Green Hydnophora

Green 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 may sting them, which may result in death of the coral.
