Nephthea sp.
Tree-shaped branching soft coral. Similar to Kenya Tree but more supple. Green and brown common. Hardy, fast-growing, adds natural feel to aquariums.
Nephthea (family Nephtheidae) is an octocoral (soft coral) distributed across Indo-Pacific reef slopes, with small polyps densely covering the tips of tree-like branching tufts, giving a bushy, cauliflower-like appearance. It shows muted creams, pinks, and greens, and because it contains internal sclerites, its surface feels slightly rough when the polyps retract. It is relatively easy to keep, favoring moderate lighting and moderate to slightly strong flow; stronger flow opens the polyps and produces attractive movement. In addition to photosynthesis, plankton feeding aids growth. It grows quickly and can spread, so trim periodically to manage it. Fragging is easy; note that it releases terpenoid compounds, so running activated carbon is advisable.
