LPS Coral
Duncan Coral.
One of the best beginner LPS (large-polyp stony) corals — fuzzy, tubular polyps in green and tan that fatten up fast when fed. Peaceful, reef-safe, and forgiving of moderate light and flow; it'll branch out into a glowing colony in a 30-gallon-plus reef.

Good tank mates
Duncan coral is a peaceful, reef-safe LPS that coexists well with fish and most other corals, and it makes a forgiving companion for clownfish, gobies, and other calm community species. It has minimal aggression toward neighbors but should still get a little space from stinging corals like hammers and torches that can sweep into it. It poses no threat to tankmates and is a fine choice for a mixed reef.
Good to know
Duncan coral readily adds new heads and polyps off the sides of existing ones, so a single colony slowly branches outward into a clustered bouquet over time.

Ultra Black Ice
Reef-safe and peaceful; does not nip coral tissue. Duncan coral (Duncanopsammia axifuga) is among the more tolerant LPS hosts when clownfish lack an anemone — Reef2Reef hobbyist consensus shows colonies typically adapt within weeks, though small or single-head frags should be monitored closely for smothering or tissue recession caused by persistent hosting activity.
Royal Gramma
Considered 100% reef-safe by all major authorities; does not nip corals, anemones, or clams. Retreats to rockwork crevices and does not interact with coral tissue, making it an ideal co-inhabitant for the rockwork-heavy low-flow environment Duncan coral thrives in.
Firefish Goby
Fully reef-safe; does not nip or disturb coral tissue. Hovers near the substrate in the same low-flow mid-to-bottom zone Duncan coral occupies without any physical contact with polyps. Note: a tight-fitting lid is mandatory as this species is a confirmed jumper.
Green Chromis
Reef-safe; ignores corals and sessile invertebrates entirely. Occupies the mid-water column well above where Duncan coral is placed. Known intraspecific dominance aggression within the school is a fish-management concern, not a coral compatibility issue.
- N
Neon Goby
Tiny (under 2 inches), peaceful cleaning-station fish that is universally considered reef-safe. Will not nip or irritate coral tissue and provides parasite-cleaning service to tankmates; no documented negative interaction with LPS corals of any kind.
