Safety: handling stylophora

Low hazard

How do you care for stylophora?

Placement

Mid to upper

Flow

Moderate to strong

Feeding

Optional

Growth

Moderate to fast

Water quality

One of the most forgiving SPS; tolerates minor nutrient swings better than Acropora typical, check

How much light does it need?

Sources put it at about 150 to 350 PAR, measured where the coral sits. No figure was published for this coral itself, so this is the usual range for its group. Start a new coral at the low end and raise it over weeks.

Adapts to medium to high light. typical, check

Invertebrates

Invertebrates that may nip corals when hungry.

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.

Pests, dips and quarantine

Red bugs possible

General SPS dip

No dip reliably kills pest eggs, so a dip lowers the risk rather than removing it. Inspect new frags with a torch after lights out, including the underside and the plug.
