Blueheaded Tilefish

Blueheaded Tilefish

The Blueheaded Tilefish (Hoplolatilus starcki), commonly called Starck's tilefish, is an elegant, torpedo-shaped fish with a luminous blue head fading into a pale yellow body. A deeper-water species that hovers above the substrate and builds rubble burrows, it brings constant, hovering movement to the lower water column of a reef aquarium and is fully reef-safe.

Its great virtue — graceful, peaceful behaviour — comes with one serious caveat: it is among the most determined jumpers in the hobby, and an open-topped tank will almost certainly lose it.

Natural Habitat & Origin

Hoplolatilus starcki lives on deeper reef slopes, typically near rubble and sand at the base of the reef, where it constructs and maintains a burrow from rubble and shelters in it when alarmed. Pairs are often seen hovering together above their burrow, dropping into it at the first sign of danger.

In the aquarium it wants a sand-and-rubble area to burrow in, some rockwork for shelter, and — above all — open swimming space above the substrate.

Care Requirements

Maintain stable marine conditions: salinity around 1.024–1.026, pH 8.1–8.4, and a temperature of about 24–26°C (75–79°F). Reaching about 15 cm (6 inches), it is best given a tank of around 280 litres (about 75 US gallons) or more with open water and a substrate it can burrow into. A completely secure, gap-free lid is essential — jumping is the single biggest cause of loss for this species. Subdued lighting during acclimation helps a deep-water fish settle.

Diet & Feeding

The Blueheaded Tilefish is a carnivore, feeding on zooplankton and small invertebrates in the water column and over the substrate. It accepts aquarium foods well: offer frequent small meals of frozen mysis and enriched brine shrimp, finely chopped seafood and quality marine pellets. Feed several times a day to keep this active, hovering fish in good condition.

Behavior & Temperament

This is a peaceful, sociable fish that does well singly or as a pair and poses no threat to tankmates. It can be shy at first, especially in a bright or busy tank, but settles to hover confidently above its burrow once established. Calm tankmates and a secure environment bring out its best behaviour.

Tank Mates

Pair it with other peaceful reef fish — anthias, smaller wrasses, gobies, cardinalfish and similar — and avoid aggressive or boisterous species that will keep it hidden. It is fully reef-safe, leaving corals and ornamental invertebrates alone, making it an excellent choice for a peaceful reef with open water for it to patrol.

Breeding

Hoplolatilus starcki forms pairs and is a pelagic spawner; rearing the larvae is beyond the home aquarium, so trade specimens are wild-collected from deeper reefs.

Common Health Issues

By far the greatest risk is jumping, so a secure, gap-free lid is non-negotiable. Beyond that the species is reasonably hardy, though, like all marine fish, it can be affected by marine ich (Cryptocaryon irritans) and marine velvet (Amyloodinium ocellatum) under stress, and it can be sensitive during acclimation. Quarantine new arrivals, acclimate gently with subdued lighting, keep water quality stable — and secure that lid — and this graceful tilefish will thrive in a peaceful reef.
