Nephthea chabrolii · Saltwater Soft Coral
What Tree Coral look like
Nephthea chabrolii, commonly known as the Tree Coral, exhibits a distinctive morphology characterized by its branching, tree-like structure that can reach a maximum height of approximately 30 cm. The polyps are small, typically measuring 1-2 cm in diameter, and are arranged in clusters along the branches, giving the coral a bushy appearance. The coloration can vary from pale yellow to vibrant green, often with a translucent quality that enhances its visual appeal under aquarium lighting. Unlike many hard corals, Tree Corals lack a rigid calcium carbonate skeleton, instead possessing a flexible, soft body supported by a network of mesenterial filaments. This species does not exhibit significant sexual dimorphism, and its defensive adaptations include the production of a mild toxin that can deter some predators, although it is generally considered non-aggressive towards tank mates. The polyps extend during the day to capture plankton and organic particles, and they retract at night, showcasing their dynamic feeding behavior.
Behavior & temperament
Tree Corals are typically found in shallow reef environments and exhibit a semi-colonial lifestyle, often forming large colonies that provide habitat for various marine organisms. They are generally non-aggressive and can coexist peacefully with other corals and invertebrates. The polyps extend to feed primarily on zooplankton and phytoplankton, utilizing their nematocysts for capturing prey. In terms of movement, Tree Corals exhibit limited mobility, relying on water currents for nutrient delivery. They are known to have a symbiotic relationship with zooxanthellae, which provide them with additional energy through photosynthesis. Breeding behavior in this species is not well-documented, but it is believed to reproduce both sexually and asexually, with fragmentation being a common method of propagation.
Diet & feeding
Tree Corals are primarily filter feeders, consuming zooplankton and phytoplankton from the water column. In captivity, they thrive on a diet of finely chopped marine foods, liquid coral foods, and phytoplankton supplements.
Behind the name
The genus name 'Nephthea' is derived from the Greek word 'nephthys', meaning 'mistress of the house', while the species name 'chabrolii' honors a specific individual or locality, although the exact origin is less clear.
