Florida and local context

REEF's cumulative citizen-science diver survey report lists Centropyge argi at Juno Ledge. This is a historical reported occurrence, not an independently reidentified voucher or an encounter guarantee. Other supplied named-site reports are preserved in the observations list. Reports cover 1/1/93–11/10/26; historical occurrence does not establish present abundance or guarantee a sighting.

A documented past record does not establish present abundance or guarantee an encounter.

How to recognize this animal

A tiny, deep-blue angelfish with a yellow-orange lower face and chest and a blue ring around the eye. The body is oval and flattened, with a short blunt snout.

Sources: Smithsonian Tropical Research Institute: Cherubfish

Size and life stages

The regional account gives about 5 cm (2 inches) as the maximum. Its small size is normal for this angelfish, not proof that it is a juvenile of a larger species.

Habitat and where to look

Found on coral and rubble bottoms. The source says records are usually below 30 m, but this is not a reason to exceed your dive plan or training.

Sources: Smithsonian Tropical Research Institute: Cherubfish

Range and local context

The account extends from North Carolina to the southern Caribbean. Local presence is documented only by the supplied named-site reports, not by assumed continuous occupation of that range.

What is on the menu?

The ecological report classifies it as herbivorous and lists benthic microalgae. Watch for picking at surfaces rather than assuming it is cleaning another fish or eating coral. Do not supply food to obtain a photograph.

Daily habits and behavior

A bottom-associated reef fish according to the compiled account. Search slowly without moving rubble. Local daily activity, territory size and group structure were not established by the sources reviewed for this draft.

Mating and the next generation

The source lists pelagic eggs and larvae. No local spawning season, clutch size or sex assignment is inferred from those categories. Color and a single size estimate do not establish the reproductive role of an observed fish.

Look-alikes and identification traps

Compare other small angelfishes, especially Centropyge aurantonotus and young rock beauties. Confirm the blue body, orange lower head and chest, and blue eye ring together rather than using small size alone.

Observe without disturbing

Photograph from outside shelter and never lift rubble to expose a fish. If the animal repeatedly disappears after your approach, back away and let it resume normal activity. Leave all surrounding habitat in place.

Harvest, protection and eating safety

Live-only ornamental collection; closed sites apply

Yellow denotes conditional live ornamental collection, never food harvest. Closed collection sites override statewide bag allowances. No year-round open season is inferred from the absence of dates.

This color is a qualified summary, not permission to collect or a guarantee that a particular animal is safe to eat.

Can it be hunted or harvested?

Centropyge argi falls within angelfishes, family Pomacanthidae. Florida recreational marine-life rules require live landing and continued live maintenance with suitable circulation, aeration or oxygenation. Where collection is lawful, the normal limit is five of a species within 20 total marine-life organisms per person daily; two-day possession is ten of a species within 40 total. A recreational saltwater license is required unless exempt; recreational sale is prohibited. The angelfish limit is five angelfish combined per person daily, within that aggregate. Do not assign Pomacanthus or Holacanthus size slots to Centropyge argi; no Centropyge size slot is stated in the reviewed table.

Florida seasons and areas

Florida marine-life requirements also apply in adjacent federal waters. Listed marine-life collection is prohibited in the mapped Blue Heron Bridge Special Marine Life Area, not throughout Palm Beach County. Pennekamp prohibits tropical-fish collection. Biscayne National Park prohibits ornamental collection except under a valid superintendent-issued collecting permit. This is not permission to seek or use such a permit. Check the exact site, not just the county. Florida Keys Sanctuary Preservation Areas prohibit fishing and collection, subject to specifically stated exceptions; the Key Largo Management Area separately prohibits tropical-fish take and spearfishing. Biscayne National Park has additional rules, including a mapped March 1–May 31 fishing closure effective in 2026. These are not whole-county bans.

Can it be speared?

Do not spear this live-only marine-life species. Use only authorized nonlethal collection methods where collection is permitted. Location restrictions still apply: spearfishing is prohibited in Monroe state waters from Long Key, including Long Key, north to the Miami-Dade line. This state-water restriction is separate from the Key Largo Management Area prohibition. Florida also restricts spearfishing around swimming beaches, fishing piers/bridges, jetties and state parks; federal water alone is not permission to spear in a closed sanctuary zone.

Is it safe to eat?

Not a recreational food-harvest fish under these live-only rules. No recipe, preparation method or food-safety clearance is provided. A harvest allowance is not a food-safety clearance. Check current Florida Department of Health advice for the capture location, species and person eating the fish. This review establishes no meal frequency and no local restaurant menu match.

This review covers the Vero Beach–Key Largo Atlantic corridor: Indian River, St. Lucie, Martin, Palm Beach, Broward, Miami-Dade and Monroe counties. Florida Atlantic state waters and South Atlantic federal waters are distinct jurisdictions. Do not extend a state-water season tag to federal waters or transfer Atlantic rules to Gulf-side Keys waters. Park and sanctuary boundaries can override a species allowance.

Before you act: Confirm the species, date, exact management area, state or federal waters, gear, licenses and current local closures. A local occurrence record never grants permission to take an animal.
