Psammocora Coral Care Guide: Encrusting SPS Variant

Psammocora is the quiet achiever of the SPS world. It lacks the flashy polyp extension of Acropora and the plating geometry of Montipora capricornis, yet it thrives under conditions that would stress most small-polyp stony corals. This psammocora coral care guide from Gensou Aquascaping at 5 Everton Park explains why Psammocora deserves a spot in any Singapore beginner’s first SPS experiment, with practical notes on lighting, flow, and why the fine, sandpaper-textured surface rewards patient observation over six months.

Quick Facts

• Scientific name: Psammocora spp., family Psammocoridae
• Care level: easy, considered beginner SPS
• Growth form: encrusting, occasionally digitate
• Lighting: PAR 100-200, moderate
• Flow: moderate, variable
• Temperature: 24-26 C, alkalinity 8-9 dKH
• Typical Singapore price: $30-60 for a 3-5 cm frag

Species Profile

Psammocora corallites are tiny, sunken, and densely packed, giving the surface a sandpaper texture that photographs beautifully under macro lenses. Colours range from olive and brown to fluorescent green, blue, and orange under actinic light. Common captive morphs include “Superman” (blue with red polyps) and “Orange Stellata”. Growth is encrusting across rockwork and frag plugs, with some species producing thick branching fingers over time.

Tank Setup

Any stable reef tank with steady parameters works. A 60-litre nano is sufficient for a frag, and the coral will encrust 8-12 cm of rock within a year. Mid-to-upper rockwork placement suits most specimens, although Psammocora also handles lower, shaded positions better than almost any other SPS.

Water Parameters

Alkalinity 8-9 dKH, calcium 420-440 ppm, magnesium 1300 ppm, salinity 1.025. Psammocora accepts nitrate 2-8 ppm and phosphate 0.03-0.08 ppm, which is slightly broader than the Acropora sweet spot. Parameter stability outranks absolute values; swings of more than 1 dKH in 24 hours can cause tip dieback on branching morphs.

Lighting

Moderate to moderately-high light is ideal. PAR 100-200 at placement drives growth without bleaching. Psammocora tolerates lower light than Acropora, which is useful in tanks where shaded rock faces would otherwise go unused. Blue-heavy spectra enhance fluorescent pigments strongly, which is why Singapore reefers often photograph these corals under pure actinic for social media.

Flow

Moderate, variable flow keeps detritus off the encrusting surface. Direct laminar flow is acceptable at modest strength, but most Singapore nano reefs run better with a random pulse pattern bounced off the glass. Dead flow zones allow detritus to settle into the tiny corallite pits and trigger tissue recession.

Feeding

Primarily photosynthetic. The tiny polyps extend slightly at night but rarely capture target-fed food. Dosing amino acids, reef roids, or dissolved coral food weekly accelerates encrustation. Overfeeding the tank is a more common risk than underfeeding the coral, because excess nutrients in tropical Singapore tanks quickly fuel algae and cyanobacteria.

Compatibility

Reef safe with all common fish. Place Psammocora away from euphyllia sweeper tentacles and from overly aggressive leather corals, which will chemically suppress growth. The encrusting habit means neighbouring corals should be on separate rocks or you will see Psammocora slowly overgrow them.

Common Problems

Rapid tissue necrosis (RTN) is rare in Psammocora compared to Acropora. Slow tissue recession from the edge inward usually signals poor water quality, allelopathy, or insufficient flow. Address by checking alkalinity stability, running fresh carbon, and improving circulation. Tissue regrowth is visible within weeks when conditions correct.

Propagation

Fragging is straightforward. Snap or saw off a piece of encrusted rock, glue to a ceramic plug, and return to moderate flow. Heal time is 1-2 weeks. Singapore fraggers list Psammocora on Carousell at $15-30 per frag, often as “Superman” or “Stellata” morphs.

Buying in Singapore

Psammocora appears less frequently than Acropora or Montipora at local shops. C328 Clementi and Serangoon North dealers occasionally stock it alongside other encrusting SPS. Inspect for full tissue coverage, vivid colour under blue light, and no white skeleton patches. Dip and acclimate before placement; our drip acclimation guide lays out the procedure.
