Soft Coral
Yellow Polyps.
Bright yellow polyps that open into a sunny carpet across the rockwork — a hardy, fast-spreading soft coral and a cheerful pop of color. Peaceful, reef-safe, and beginner-easy; give them moderate light and flow in a 10-gallon-plus reef.

Good tank mates
A peaceful, beginner-friendly soft coral that is reef-safe and coexists with fish, shrimp, snails, and most other corals. Give it a little space from neighbors since a healthy colony spreads across the rock over time and you don't want it overgrowing slower corals. Keep an eye that fast-growing corals or aggressive stinging neighbors don't crowd it out.
Good to know
Yellow polyps are colonial animals that reproduce by budding, slowly carpeting live rock with bright yellow flower-like polyps.

Ultra Black Ice
A textbook reef-safe fish with no documented history of nipping or consuming soft-coral polyps. Water parameters overlap precisely with zoanthid-type reef setups, and its peaceful temperament poses zero aggression risk to sessile invertebrates.
Royal Gramma
Mid-water, cave-dwelling basslet that is unambiguously reef-safe; it does not interact with sessile invertebrates at all and presents no aggression toward other peaceful reef inhabitants in appropriately sized tanks.
Firefish Goby
Docile, hovering fish that stays in the water column and has no predatory or nipping interest in corals or polyps. Fully compatible saltwater parameters and temperament.
Green Chromis
Confirmed reef-safe planktivore — multiple sources including Reef Chasers and Fishkeeping World confirm it does not nip corals or polyps and feeds exclusively on zooplankton. No documented coral predation in the literature.
Yellow Watchman Goby
Reef-safe bottom dweller with no nipping or predatory interest in polyps. Burrowing behavior can physically displace polyps placed loose on the sandbed, so colonies should be secured to live rock — not a predation issue, purely a placement one.
