Notes: “The most insane Indo Elegance I have ever seen,” says ACI’s Chris Meckley when showcasing this coral during a livestream in July, 2020.  “Black, with gold tips, green tips, and orange tips, unbelieable. It’s a monster, at least 15-18 inches (38-46 cm) across.” This coral was shipped across the country and now resides in a display aquarium in California.

Lined Dartfish
Ptereleotris grammica

A deepwater species that is a good candidate for the peaceful reef aquarium, the Lined Dartfish is an Indo-Pacific fish that reaches a length of about 4 inches (10 cm) and feeds on zooplankton in mid-water. Read more about this and other dartfishes, genus Ptereleotris, in Scott Michael’s feature article in the September/October, 2020 issue of CORAL Magazine.

Ruby Dragonet
Synchiropus sycorax

Having only been collected for the aquarium trade in the last decade, the Ruby Dragonet has become a reef aquarium favorite: it is visually stunning when in full display mode, it’s small and will eat readily if fed the proper micro-predator foods, and it even carries an exotic scientific name. According to lead author Yi-Kai Tea who described it in 2016, “The species is named after the red-robed and caped Sycorax warriors from the BBC sci-fi series ‘Dr. Who,’ in showing similarities in both coloration and grandiloquence of their garb. The epithet sycorax is a noun in apposition.” Since its debut in the aquarium trade, Synchirpus sycorax has been tagged with various common names: Ruby Red Dragonet, Ruby Dragonette, Sycorax Mandarinfish, and more.

FLOWER URCHIN
Toxopneustes pileolus (Lamarck, 1816)
Distribution: Indo-Pacific, East and South Africa to Australia, Indonesia, Philippines
Maximum Size: 20 cm (8 inches)

It may be lovely to behold, but this Indo-Pacific sea urchin can inflict paralyzing stings and it has been implicated in the deaths of divers who touched the blossom-like pedicillaria. These defensive appendages can grasp the soft tissue of a victim and release two or more toxins that can cause excruciating pain, shock, coma, and even death.

In 1935, Japanese marine biologist Tsutomu Fujiwara unwittingly picked up Flower Urchin brought to the surface in a fisherman’s net and later reported: “Instantly, I felt a severe pain … and I felt as if the toxin were beginning to move rapidly to the blood vessel from the stung area towards my heart. After a while, I experienced a faint giddiness, difficulty of respiration, paralysis of the lips, tongue and eyelids, relaxation of muscles in the limbs, was hardly able to speak or control my facial expression, and felt almost as if I were going to die. About 15 minutes afterwards, I felt that pains gradually diminish and after about an hour they disappeared completely. But the facial paralysis like that caused by cocainization continued for about six hours.”
—Tsutomu Fujiwara (1935). “On the poisonous pedicellaria of Toxopneustes pileolus (Lamarck)”. Annotationes Zoologicae Japonenses15 (1): 62–68.

Blue Cespitularia soft coral cultured by ORA in Ft. Pierce, Florida.

Featured in CORAL, January/February 2020

ORA’s Blue Cespitularia is a glittering, iridescent example of an exceptional octocoral cultivar made more accessible through intensive aquaculture efforts.

According to ORA: Blue Cespitularia is sometimes referred to as Blue Xenia. The variety ORA grows is a unique color form that has a turquoise body with elegant peachy – orange polyps. The color intensity of this soft coral varies greatly and is dependent of lighting conditions. In some settings the ORA Blue Cespitularia develops to have a sparkling metallic quality similar to very fine glitter.

Placement: All Levels
Lighting: Low – High
Flow: Moderate – Strong

Blue Cespitularia (Cespitularia sp.)

Aeolid nudibranch (Phyllodesmium rudmani), which perfectly mimics a small colony of Xenia Soft Coral. Also known as a solar-powered sea slug. Found throughout Indonesia and Philippines. Photo taken off Anilao, Philippines, within the Coral Triangle. Image: © Gary Bell / OceanwideImages.com

From the January’February 2020 Issue of CORAL Magazine: An amazing example of marine mimicry, this remarkable sea slug has evolved to appear as a perfect match for Xenia sp. soft coral. This species grows to about 4.5 cm (1.8 inches), and aquarists may find it hitchhiking into their reefscapes on imported colonies of Xenia. Sea slugs have a paired set of antenna-like sense organs called rhinophores, which can be spotted in this image upon careful inspection.

Phyllodesmium rudmani is reported to have photosynthetic symbiotic Symbiodinium zooxanthellae in its tissues.

Read a good account in the always informative Sea Slug Forum, which says: “This solar-powered aeolid is a remarkable mimic of the Xenia colonies on which it feeds, often nestling in cavities it has burrowed out in the base of the colony.”

Leptastrea sp. Stony Coral, “Reef Raft Polkaroo” from Jason Fox Signature Corals. Possibly a color morph of Leptastrea purpurea.

Leptastrea is a genus of encrusting reefbuilding stony corals from the Indo-Pacific. Previously assigned to the family Faviidae, it has been moved to uncertain status, Scleractinia incertae sedis, based on DNA testing.

CORAL Volume 16, Number 2, March/April 2019.

Writing in CORAL Magazine, Advanced Aquatics, March/April 2019, researcher Samuel Nietzer says:

“Leptastrea purpurea has an extensive distribution and can be found from the reefs of the western Indian Ocean to the Indo-Pacific Coral Triangle to the Hawaiian Islands. 

“The most astonishing and unique feature of L. purpurea is not, however, its apparent adaptability but its reproductive strategy: so-called brooding, in which parent colonies harbor their growing progeny before releasing them. The extraordinary thing about the reproduction in this species isn’t, however, the strategy, but the daily release of larvae. This circumstance makes L. purpurea a particularly suitable species for performing experiments with planula larvae.”
