About

The branched tree coral (Parastenella ramosa) is a soft coral native to the Eastern Central Pacific, where it forms its characteristic branching, arborescent colonies in moderate-flow reef environments. The structure is what immediately catches your eye. Multiple arms radiate outward in a tree-like pattern that gives this coral both its common and scientific names. In the aquarium, it tends to be a relatively forgiving choice, which is welcome news given that many soft corals with this kind of architectural form can be temperamental. Moderate lighting and moderate flow suit it well, and reef safe status means you can place it without worrying about it bothering neighboring corals or inverts. That said, placement still matters. You want good water movement reaching all the branches to prevent detritus accumulation and encourage healthy polyp extension. As with most soft corals, consistency in water quality matters more than chasing perfect parameters. Colonies can become a genuine focal point in a mixed reef, providing vertical structure and a sense of natural complexity that flat or encrusting corals simply cannot replicate. If you are building out a Pacific-themed display, this one fits the brief nicely.

Care guide

Position Parastenella ramosa where moderate flow reaches all branches evenly to prevent detritus buildup and promote full polyp extension. Avoid direct, turbulent flow that can damage delicate branching structure. Feed small particles or rely on natural plankton if your system is well-established; most soft corals benefit from occasional target feeding with zooplankton. Keep water quality stable rather than obsessing over exact parameters. Consistency matters more than perfection. Ensure moderate lighting penetrates the colony without causing stress. Watch for polyp retraction, which often signals inadequate flow or water quality dips rather than a need for adjustment. Its reef-safe nature means peaceful cohabitation with other corals, but provide sufficient spacing to prevent physical contact. Prune or remove dead branches if they accumulate to maintain colony health.

Breeding

Propagate Parastenella ramosa by careful fragmentation of branches during stable tank conditions. Healthy, established colonies are easiest to frag; use clean, sharp tools to make cuts between branch junctions. Frag pieces typically need 6–12 weeks to form a basal disk and establish on rubble or rock. Provide identical conditions to the parent colony: moderate flow and lighting. Success rates improve in mature tanks with stable water chemistry. Most hobbyists find fragging easier than growing from small fragments, so start with decent-sized pieces from robust colonies.
