Sarcophyton glaucum: living card for the toadstool leather coral

Sarcophyton glaucum (toadstool leather coral) can look closed during a normal shed. The useful skill is distinguishing renewal from real decline.

Quick read

• Type: leather soft coral.
• Aquarium: stable reef with activated carbon if many soft corals are present.
• Light: medium.
• Flow: moderate, useful for removing shed film.
• Indicative temperature: 24-26 C.
• Salinity: 1.024-1.026 SG.
• Alkalinity: 8-10 dKH.
• Calcium: 400-450 mg/L.
• Difficulty: low-medium; needs space and patience.

What to check before placing it

Look for a firm foot, tissue without deep wounds, and polyps that have opened at least in the shop. Avoid black or disintegrating bases.

Before gluing a colony, think about its future size, the direction of flow, and whether you could remove it without dismantling half the rockwork if something goes wrong.

Placement and coral reading

Leave room for umbrella-like growth. Flow should clean the surface, not bend the stalk all day.

Read the first week outside the blue-light photo. Watch extension, tissue, response to flow, and irritation signs when the aquarium is in its normal rhythm.

Working parameters

It tolerates some variation but benefits from regular changes and stability. In mixed systems, carbon helps manage soft-coral compounds.

In a reef, stability means repetition: salinity, alkalinity, temperature, and nutrients inside a window the aquarium can sustain, not perfect numbers from one test.

Compatibility and warning

Do not place it against delicate SPS or LPS that can sting it. Its competition is chemical and spatial as well as direct.

A shiny film for days may be shedding; tissue melting, bad smell, or a black base is a real warning.
